Yes, but also no. Each time Microsoft slips, you do see the waves of folks migrating and a lot of big projects—like KDE, GNOME, Freedesktop—have moved elsewhere since ’16. My concern is more on the education side where schools are starting kids on the proprietary service and YouTube ‘gurus’ saying you need it which might make its growth outpace folks leaving after all these the outages, or some new EEE initiative, etc. that have historically caused migrations. The other concern is communities that have used Microsoft GitHub IDs for identity in the community (i.e. Elm requires all public packages are published to Microsoft GitHub and your user ID is the an identifier, Nixpkgs requires the ID for its maintainers.nix, Unison Share accounts requires sign-ins via Microsoft GitHub, etc.).

While I totally disagree with the forced proprietary collaboration (need an account & can’t contribute without, nor can you self-host or fork to fix the platform) of Microsoft GitHub, at least unlike the Discord situation it is search indexable, reading doesn’t require an account or JavaScript, and is strictly public communication (no DMs floating around). Once you start buying into the larger platform though, the corner for yourself has been painted in—but that’s not to say you couldn’t have mirror that accepts merge requests without an account or still have a mailing list/inbox to mail patches to. (But, like, just set up your project elsewhere in the first place and stop playing into a social media platform masquerading as a code forge—as well as let folks sign up with email or WebFinger)
