He doesn't prohibit them because he can't. He directly says as much in the second line of his piece. IF he could limit you, he would.

He then goes on to say that he won't permit his software to be compatible with other platforms like Visual Studio, _even at the cost of performance_.

If that's not cutting your nose off to spite your face, it's still definitely a direct attempt to limit your freedom.

No, he doesn't say that if he could he would limit you and that he won't permit his software to be compatible.

He just says that he won't do it and explains why you should not either. That's hardly limiting you from doing anything.

Even though I don't agree with his position (I fit in the "I don't care if it works on Windows or not, if you care pull requests are always welcome" camp), it's a reasonable one to have.
