Well it’s because computer science has been around for 60+ years and computers are binary machines. It was natural for everything to be base 2. The most infuriating part is why drive manufacturers arbitrarily started calling 1000 bytes a kilobyte, 1000 kilobytes a megabyte, and 1000 megabytes a gigabyte, and a 1000 gigabytes a terabyte when until then a 1 TB was 1099511627776 bytes. They did this simply because it made their drives appear 10% bigger. So good ol’ shrinkflation. You could make drives 10% smaller and sell them for the same price.

Pretty obvious that you didn't read the article. If you find the time I'd like to encourage you to read it. I hope it clears up some misconceptions and make things clearer why even in those 60+ years it was always intellectually dishonest to call 1024 byte a kilobyte.
You should at least read "(Un)lucky coincidence"
Ok so I did read the article. For one I can’t take an article seriously that is using memes. Thing the second yes drive manufacturers are at fault because I’ve been in IT a very very long time and I remember when HD manufacturers actually changed. And the reason was greed (shrinkflation). I mean why change, why inject confusion where there wasn’t any before. Find the simplest least complex reason and that is likely true (Occam's razor). Or follow the money usually works too.
It was never intellectually dishonest to call it a kilobyte, it was convenient and was close enough. It’s what I would have done and it was obviously accepted by lots of really smart people back then so it stuck. If there was ever any confusion it’s by people who created the confusion by creating the alternative (see above).
If you wanna be upset you should be upset at the gibi, kibi, tebi nonsense that we have to deal with now because of said confusion (see above). I can tell you for a fact that no one in my professional IT career of over 30 years has ever used any of the **bi words.
You can be upset if you want but it is never really a problem for folks like me.
Hopefully this helps…
kilobit = 1000 bits. Kilobyte = 1000 bytes.
How is anything about that intellectually dishonest??
The only ones being dishonest are the drive manufacturers, like the person above said. They sell storage drives by advertising them in the byte quantity but they're actually in the bit quantity.
If a hard drive has exactly 8'269'642'989'568 bytes what's the benefit of using binary prefixes instead of decimal prefixes?
There is a reason for memory like caches, buffer sizes and RAM. But we don't count printer paper with binary prefixes because the printer communication uses binary.
There is no(!) reason to label hard drive sizes with binary prefixes.
So here’s the thing. I don’t necessarily disagree with you. And if this had done from the start it would never had been a problem. But it wasn’t and THAT is what caused the confusion. You put a lot of thought and research into your post and I can very much respect that. It’s something you feel strongly about and you took the time to write about your beef with this. IEC changed the nomenclature in the late 90s. But the REASON they changed it was to avoid the confusion caused by the drive manufacturers (I bet you can guess who was in the committee that proposed the change).
But I can tell you as a professional IT person we never really expect any drive (solid state or otherwise) to be any specific size. RAID, file system overhead, block size fragmentation, etc all take a cut. It’s basically just bistromathics (that’s a Hitchhiker’s reference) and the overall size of any storage system is only vaguely related to actual drive size.
So I just want to basically apologize for being so flippant before. It’s important enough to you that you took the time to write this. It’s just that I’m getting rather cynical as I get older and just expect the enshittification of every to continue ad infinitum on everything digital.
A lot of people are replying as if OP asked a question. It's a link to a blog post explaining why a kilobyte is 1000 and not 1024 bytes (exactly as the title says!). OP knows the answer, in fact they know it so well they wrote an extensive post about it.
Thank you for the write up! You should re-check the spelling and grammar as some sections had some troubles. I have a sentence I need to go to the post to get, so let me edit this later!
Edit: the second half of this sentence is a mess: "The factors don’t solely consist of twos, but ten are certainly lot of them." Otherwise nothing jumped out at me but I would reread it just in case!
I also assume that people are answering that way because they thought it was a question.
However, it's also possible that they saw it described as a 20 minute read, and knew that the answer actually takes about 10 seconds to read, and figured that they'd save people 19 minutes and 50 seconds.
It's true that the actual "story" is very short. 1 kB is 1000 bytes and 1 KiB is 1024 bytes. But the post is not about this, but about why calling 1024 a kilobyte always was wrong even in a historical context and even though almost everybody did that.

Yes. But it does raise the question of why you didn't say that in either your title:
Why a kilobyte is 1000 and not 1024 bytes
or your description:
I often find myself explaining the same things in real life and online, so I recently started writing technical blog posts.
This one is about why it was a mistake to call 1024 bytes a kilobyte. It’s about a 20min read so thank you very much in advance if you find the time to read it.
Feedback is very much welcome. Thank you.
The title and description were your two chances to convince people to read your article. But what they say is that it's a 20 minute read for 10 seconds of information. There is nothing that says there will be historical context.
I get that you might want to make the title more clickbaitey, but why write a description out if you're not going to tell what's actually in the article?
So, that's my feedback. I hope this helps.
One other bit of closely-related feedback, for your writing, in general. Always start with the most important part. Assume that people will stop reading unless you convince them otherwise. Your title should convince people to read the article, or at least to read the description. The very first part of your description is your chance to convince people to click through to the article, but you used it to tell an anecdote about why you wrote the article.
I'm the kind of person who often reads articles all the way through, but I have discovered that most people lose interest quickly and will stop reading.
I tried to make the title the exact opposite of clickbait. There are no unanswered questions on purpose. No "Find out if a kilobyte is 1024 bytes or 1000 bytes". I think people are smart enough that I not just reiterate for 20min why a kilobyte is 1000 bytes but instead go into more details.
The main problem is probably that people won't sacrifice 20min of there time on something they are not sure if it's a good read but the only thing I can do is trying to encourage them to read it anyway.
There are not ads, no tracking, no cookies, no login, no newsletter, no paywall. I don't benefit if you read it. I'd like to clear up misconceptions but I can't force people to read it.
I don’t benefit if you read it.
You don't benefit financially, but there are other benefits. For example, you specifically asked for feedback, and you have received some.
