Github was scary enough just as a monolith of FOSS code. In microsoft's hands, it's terrifying: they have shown lack of integrity in the past that makes their current professions (and examples!) of civilized behavior suspect.

Is your project dead or is it just that Github et all the PR's others sent? Is your project discoverable there or is it buried in irrelevant search results?

Could Microsoft open some of their older code? a FOSS (as far as possible) Win2k would still be of value to the world.
