Remember when people used to think we were crazy regarding advertising based on speech secretly recorded?

I do this fun thing I've dubbed the "platypus test" to show people how crazy it is. If you open Instagram and scroll through reels while talking gibberish adding the word platypus every now and then you will eventually start seeing them in your feed. Its rather quick too, I managed to get results within 10 minutes.

I still think it's bogus unless I see clear proof of it. That would imply your Instagram app somehow needs to bypass the kernel which let's the system know when the microphone is being used (some OS let's you know when mic or app is accessed real-time). That seems like an awfully open backdoor to microphone access.

Go try it out and let me know your results. Just for context I'm using GrapheneOS. And yeah I know some hardware backdoor would seem paranoid but consider the reach of said company.

I have, repeatedly, because it's not the first time I hear of this, only once did something similar to what I was saying appeared. Sounds like a coincidence to me.

Happens a lot when you talk about burgers or pizza and you get an ad for whatever you're talking about.
You can say that's coincidence, and yes these chains do a lot of ads.
Then one day I'm looking at food to order (I have all the ad/tracking blockers) while my GF is on her laptop doing something completely different.
I mention how bad restaurant X is. (there's only one, not a chain)
And in 2 minutes she gets the ad for that particular restaurant.
Really, history has shown over and over that you can't trust tech companies.
