The reason people cite when defending Github usually isn't the repisitory hosting itself, but the extra features like oull request management and issue tracker that also generate massive network effects by enabling the same accounts to participate in all public projects. Github is nore of a social network posing as a development tool.
Also remember "git" is decentralized itself, you're supposed to have your git repo locally too, if PR's, or issues or comments are "alpha" your code shouldn't be affected by it at all
Im personally down to try alpha software usually, i just havent found the need to retrain all my muscle memory to not use GH yet, as much as I hate it's owned by microsoft nowadays.
They also do offer pretty good "free tier" services for CI via Actions that otherwise you'd need to pay yourself
Also, I moved about 10 repos to a private Forgejo installation with pretty average (non-trivial) GH actions workflows. Zero repos has workflows running oob (java, .net, node). The moat is a bit there.
A feature, not a bug. If I go to a website meant to distribute source repos (git, etc), I expect them to be FOSS. Also, the title mentions 'EU Open Sources [...]' so this is irrelevant to the topic at hand.
Either way, perfect is the enemy of good, and this is good. You can find hypocrisy or lack of perfectionism anywhere.
Git repos are distributed by design. I bet all the contributors have at least 1 branch (probably closer to an average of 3) of this project on at least 1 computer that they own.
It is actually an model that has been developed in collaboration with entso-e by Open Energy Transition. You can read more about it here: https://open-tyndp.openenergytransition.org/
I guess if the github UI becomes critical to their continued development or PR then they expose themselves to a potential rug pull by github/microsoft.
I do not know much about the project so I can not tell if that is concern or if there is some other concern at play here or if those concerns apply to this project or not.
Those are the types of details I wanted to see in the comment.
