If you use GitHub as just a software forge then sure you can find an alternative. But I suspect more people use GitHub for its social aspects and they will stick around despite the regressions because building an alternative to an established social network is incredibly difficult if not impossible.
You can get work done on any software forge. But potential employers will still ask for your GitHub. People will judge your personal project by its GitHub stars and be less reluctant to download a binary from GitHub than elsewhere. Potential contributors will leave a PR on GitHub but probably not if they have to make an account on a new platform and learn how it works.
And of course, let's not assume any competitor can just absorb even a fraction of the traffic GitHub receives without suffering similar reliability issues.
