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.

Great channel covering and advocating right to repair, Lewis Rossman
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.
A complete set of security screw bits is ~20 bucks and they're far more useful than I realized until I acquired them.
Comon, do some reading:
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.
