It's remarkable that pretty much every feasible design has some traction. You might expect it to be winner-take-all.

A lot of them are designed specifically to make it difficult for the average person to open without specialized tools.

I suspect the tool industry has a strong incentive to keep as many of them as possible in use.

I have a feeling that they push new designs to manufacturers as being 'tamper-proof', then once sufficiently adopted, push them to the sales channel to be open to open these tamper-proof screws. Repeat as needed to keep revenue up.

I'm partial to Mortorq, or at least drawn to the name... https://yarn.co/yarn-clip/ccaafc61-fd54-4904-aa97-e73e532da9...

Do you find yourself stripping Phillips head acres frequently? That is because you are confusing Phillips and Pozidriv heads. They look similar but have a different head and different amount of engagement.

I just bought myself some Wiha drivers after years of using shitty tools. I am so much happier now.

Not to mention they could also have metric and imperial systems like hex keys...

I think it's a case of it being counterproductive to try to standardise.

Some of it is to thwart legit owners of things, but also a fair amount to deter casual vandalism or even saboteurs.
