That’s just not true. Tons of people use a Mac as a software development machine and virtually zero of them install a non-macOS operating system. All it has to do is run Docker and people will continue developing Linux software on it. That said I don’t think Apple is planning on locking down macs, simply because they have never done so (at least not in the modern era), whereas they have always done so with i-devices. Sure there’s always a chance they could change one practice or the other but there’s no good reason to believe they will.
