Whether it be electronics, automobiles or medical equipment, the manufacturers should not be able to horde “oem” parts, render your stuff useless if you repair it with aftermarket parts, or hide schematics of their products.

Basic blender went bad (motor ran but spindle wasn't rotating). I wanted to disassemble to see if it could be repaired. Three of the four screws were Phillips head. I had to cut the casing open in order to discover why I couldn't unscrew the fourth. It was a slotted spanner.
Buy a security bitset! It is surprisingly handly to have around. Sometimes, I've needed a certain screw size that they don't have in imperial, but they do have in metric at the hardware store. But it's a security bit only.
They also work on regular, non security bits in a pinch.
Comon, do some reading:

They didn't have to, somehow this was screwed in and it wasn't magic.
What brand?
Harbor freight has sets of tamper resistant bits. They are also handy for regular Allen and torx heads.
A complete set of security screw bits is ~20 bucks and they're far more useful than I realized until I acquired them.

Do some comprehending. Yes he had to do that. But it was because he was using the wrong bit.
He had to see which bit to use
That can be accomplished non-destructively.
If you haven't already, look into getting a ratcheting screwdriver with replaceable bits, and a pack of various bits for it. Idk where I got it, but I've got all kinds of screwy bits (including the H-bit head) that I need very infrequently, but I'm always happy when I do and I already have it.
I think the bit pack I got was for the security torx and it came with a bunch of other stuff.
I've found my ratchet driver is surprisingly often too thick to get into those screw holes of many electronics. There are thinner ones available, maybe go for those
