Uh, no. Major distributions have adopted his software into the core of their product and it is virtually impossible to substitute it. These distros happen to be the only approved vendors for most major private and public sector commercial software. We're not free to not use it.

See above.

Besides the fact that most of the Linux kernel dev team thinks he and his cronies are asshats? Besides the way he's designed his software to be the polar opposite model of the operating system he's building it for? Besides the fact that he's insulting all of the people he purports to write software for and with, ignoring the fact that almost no one else has been treated this way?

Besides all of that, it's a troll because he's basically just said 'fuck you' to everyone who develops open source software and now his fanboys and detractors are all arguing over it. It's a very effective troll indeed.
