They own Typescript? I wasn’t aware that they control the organization, but that ought to be easy enough to fork. NPM is a bigger one, but also not too huge. Azure is only used by people who already have Microsoft/Windows buy-in.
I genuinely don't know, got curious and went to typescriptlang.org to find some "About" page or "Governance" or something else, but couldn't find anything at all about it. It was exclusively developed by Microsoft for two years, and with no other clear governance/decision structure today as far as I can see, doesn't that exactly mean that Microsoft controls the entire "organization"? It's not clear what "organization" you're referring to either, the GitHub organization? I'd assume that's also 100% Microsoft controlled.
