It’s not that. It’s that their lawyers won’t let the engineering side distribute gnu tools. Period.

At Apple, if you even use GPL tools in your workflow you have to seek approval, and most often there’s pushback of “why won’t this (alternative that isn’t GPL) work ?”

Their lawyers aren’t stupid, they understand the GPL and its limits, but they’re simply doing a risk assessment- which one is less risky, the GPL variant or the BSD. For a corporation, that’s generally BSD.
