I mean, it's always kinda played off like he turned coat. But if you know the history it makes total sense.

He started off with GNOME, got interested in .net and Mono (originally as a means to integrate them into GNOME/GTK) and shifted focused on those. He built a company around that (with others), which then got bought by Microsoft due to their obvious interest in .net (and probably internal talks about the future direction of .net Core). Since then until 2022, his work was mostly on .net and its open ecosystem.

So it's neither contradictory nor counter to his roots, but is humorous when you say "the guy who created GNOME works for Microsoft". Despite the fact that he probably did some major work on bridging the two worlds together and leading to modern MS actively incubating and contributing to Open Source projects.
