Why wouldn’t they? It’s an efficient design, and aside from the whole force thing they seem to be working with the same physics that we are. Why wouldn’t they invent philips head screws?
Torx is cool and all but all the touted virtues such as less cam-out go out the window if you have to drive them in at wonky angles, like tight fitting spaces. If you gotta angle the driver it’s not gonna seat well at all, apt to jump and wear out your bit. And if your only T20 rolls away and falls under a deck, yuck, 10mm problems.
Phillips has a place and that place is ‘a wonky place to hold a power drill’. That said I’m a huge fan of square head because it’s a happy medium between those two

If you have ever used torx once in your life you can’t say that Philip is great anymore.

Angled screws only work halfway well with Pozidriv
or Torx, standard Phillips 
slip too.
Btw, why is Torq-set
or Tri-wing 
so uncommon? They seem the best mechanically.
