By this logic, you want a complete monopoly of a single platform? Because that’s the only possible way to have “no barrier”. Unless GitHub starts federating with some kind of standardized protocol. This is a huge technological and monetary barrier for GitHub, which is why it will never happen on its own, so if users are not willing to try platform-independent workflows then the problem is frankly not the competing platforms.

This is only true for the merge request workflow and not at all a problem for the patch workflow, which can work entirely via email (and is in my eyes simpler). Have a look at https://git-send-email.io/ if you want to learn about it. This is the true decentralized spirit of git. :)

There are many good replacements, you just need to stop using Github :)

Some examples: Forgejo/Gitea (self-host or hosted eg. codeberg.de), Gitlab (self-host or hosted), Sourcehut (self-host or hosted eg. sr.ht)

That is answered in the original post, the author is just doing this for fun and learning. :)
