so this only half thought and I should go to bed but

you know, microsoft is definitely not the most evil corporation out there anymore (tyvm zuckerberg) but I feel like they might be the most dangerous for FOSS, lots of their FOSS efforts are sketchy (VS Code downloading blobs on compilation, and WSL is just 'embrace extend extinguish' making a comeback)

that being said, they really can't make github more proprietary. Arguably this doesn't really change anything for github.
