You mean like forcing people to use email to submit pull requests to your self-hosted git repos?

I think he meant "you" as in there person running the project, not a contributor.

But... it's still stupid because GitHub doesn't force a workflow on you. Unless he means "have an issue tracker" and "use CI" are a workflow. You don't even need to use merge requests if you don't want (but I have no idea why anyone would give up something that works so well).

The majority of the post comes across as someone who just doesn’t like the forge sites and aside from the trust aspect, then spent a bunch of effort trying to create associations and limitations between things that don’t exist.

Definitely.
