Yeah but only MS/GH have the resources to maintain a viable project here. Little old you and me aren’t really going to reasonably fork something and have the time to maintain it.
Hm, I wouldn't say so for the superlinter specifically. If you actually look at the source, it doesn't seem particularly hard to maintain.
As if licenses mean anything. What exactly does forking by you?
the ability to use an old working version if the maintainers make breaking changes - which will at least buy you enough time to move to something else
