Cool - philips head would also just be nice since pretty much everyone has one of those.

Also - it might be nice if Apple allowed competitors to manufacture pentalobe screwdrivers themselves.

Phillips head are genuinely terrible. Pentalobe and similar are far less likely to have stripped heads.

And maybe check Amazon before saying Apple is preventing third party screwdrivers. There are hundreds there.

So, no technology that others own the patent/license to is allowed to be incorporated into any product?

I don't think you're arguing from a good place - specific concerns have been called out about pretty specific design flaws from Apple. Instantly upgrading those criticisms to a full generalization about all components in the phone doesn't feel particularly constructive.

Do I think that Apple shouldn't use some proprietary thermal paste to mount their heatsinks? I don't really care and I don't think anyone here does either - but the tools to get general access to the device body are a different matter... they're necessary for a wide range of relatively simple repair operations.
