> I don't think Apple would be removing UNIX-like tools from macOS even without certification. They know how valuable it is that most developers use their systems.

I hope you're right but I'm not as confident. Corporations - Apple included - have been guilty of some surprising ignorance when it comes to things like this. I'm thankful for this certification circus to continue so that we don't need to test your theory.

Yeah, except Apple dogfoods macOS to build most of the software for Macs and everything else they make. Presumably they rely on UNIX-like tools and would have to retool as well. So why mess with what’s working for them and others?
