There's this whole concept of "Embrace, Extend Extinguish", that a lot of people in the open source community hasn't forgotten about, and therefore find it hard to trust anything that Microsoft is about.

What's the most recent thing Microsoft extinguished?

Probably Atom

I mean it never really took off an VS Code is a great replacement. It's not clear if Atom would've gone anywhere even if MS didn't buy Github.

I think atom was going down before Microsoft bought GitHub ?
