I prefer to compare apples to apples. Git is distributed. If you host your repo on Github, you can very well just push that same Git repo to Sourcehut or your private Git server.

But otherwise, yeah, I would warn against potential vendor lock-in, especially if that service is not open-source.

Yeah, the lock-in will come with CI & and the pull-request model that requires an account in this case. The former Microsoft GitHub largely ate all the competition with its own ‘free’ (gratis) offering in Actions, but you could seek out a different CI or self-host. The latter could be easily circumvent by offering a mailing list or maintainer email—or mirror elsewhere—but it’s rare to see this with projects on Microsoft GitHub.

Well, and joining most discussions require an account, and if your alternative communication platform is Discord, we see all the same issues of lock-in.

Matt Lee’s quote comes from an article about why you would want to leave the walls of Microsoft GitHub. I would agree that would be ideal too, but developers are even more reluctant with that one—if you think suggesting libre coms gets you a downvote here, try suggesting not Microsoft GitHub.
