Because it's Microsoft. Categorically incapable of respecting their users.

What's interesting to me is how many people went like 'Oh, Satya really gets open source, this time it will be different'.

always noticed way too much reverence for satya because of what he did to valuations. i personally cant stand azure/365/all of it. i reserve no reverence for satya, he's playing a game in a class/world none of us can even relate to so i don't even see the point in talking about his achievements. looking back, it unequivocally sucks that microsoft acquired github.

I am not sure it is that. The job of Microsoft is to satisfy shareholders. That is the only target. They only care about users to the extend that helps the shareholders.
