The only reason they’re so common is because of Henry Ford. Ford wanted Robertson screws, but Ford also wanted to make his own screws in-house. Robertson wouldn’t license them, Philips would, the rest is history. Robertson screws are much more common than Philips up in Canada (where they’re from).
Comment on Philips shouldn't exist. Torx plus is the best fight me

Because Philips screws were supposed to cam out, to stop overtightening on airplanes.
Maybe we shouldn’t use Philips screws for non-aviation purposes.

Robbies are a different kind of pain due to metric and imperial sizing
BCsven@lemmy.ca 2 weeks ago
? Is this sarcasm. Robertson’s aren’t imperial or metric, they are numbered

It’s Allens that aren’t in arbitrary sizes but their actual dimensions and sold in metric and normal sizes.

the other commenter was right, I was misremembering and had hex keys in mind

Right but for aircraft we’ve got torque wrenches which can stop overtightening much more accurately.

I’ve read this was the justification after the fact.
