Some amount of screw head variance is “I want to make it harder for users to open my product so they are less likely to break it” (e.g., Nintendo GameCube controller used tri-wing screws)
Also the very existence of “security” styles is presumably to keep laypeople out of high security areas.
But I agree there is some change that could be made. Philips in particular leaves a lot to be desired; it’s so easy for them to strip.

Which is why Canada uses Robertson in construction, which allows a screw to be driven pointing up.
Phillips heads are designed to cam out to prevent over-tightening. Many who strip Phillips screws are actually using Phillips drivers on JIS (Japanese Industry Standard) heads. They look similar.
