Well, don’t forget that a philips head screw was designed to slip. It was designed as a poor man’s torque-controlled screw. This is really part of the problem. If you use hardened steel drivers and screws this is not a problem but often it’s pretty low quality and the slipping will cause damage to the head and driver.
I prefer torx for this reason. But most of the screws I use I don’t pick, because I do a lot of repair work.
Yep, it reduces cam-out. Not very well, but it does better than a slotted screw made by a drunk apprentice with a dremel being torqued with a flat-head prybar. Torx, Allen, and Robertson all reduce cam-out far more, but Phillips still sadly get used in new products.
Phillips was designed to be simple to cut and self-centering, so it could be used on assembly lines. It exploded in popularity just as mass manufactured goods were becoming popular purchases.
Later styles like square, Hex (cut) fasteners, or 12-point (both types) or Torx can create higher torque without slipping but are not centering the way Phillips is.

Phillips was not designed to cam out. It cams out so people started saying it was designed to cam out.
Phillips was designed to reduce cam out, which it does, compared to slotted.

Common misconception.
