The tamper proof screw is NOT there to protect you, It's there to discourage repairs plain and simple.
Point to where I said it was there to protect you. It's quite literally to avoid lawsuits putting the screw there implies it's meant to be taken apart by a professional, not Ted down the street who stopped school in third grade.
All they have to do is point to that screw and the lawsuit dies then and there no further action.
It's also not planned obsolescence in this case, it's a barrier to repair. Literally a hoop too small to jump through that catches the dumbest of the well meaning. It would be planned obsolescence (arguably) if it prevented repair, it doesn't it simply complicates it. It's the same reason your seatbelt part ≈00 is held down by a large torx t50-60 and no longer a 15mm bolt.
