I really doubt that. People have been hating on GitHub for years or even decades. GitLab at some point very publicly wanted to become "the world's most trusted place for open source software" but I think they gave up, or at least pivoted to AI.

GitHub has one massive advantage which is even people in HR know programmers use it, and they can just glance at a candidate from GitHub. For as long as this remains in place, GitHub will survive.

I would rather use GitLab, honestly. Forgejo, Codeberg, etc, have a CI/CD modelled after GitHub actions which I really don't like, but I digress.
