Well, it is actually kind of "understandable" if you look at this here. It looks more like an advice from there lawyers to go this way. Since Linux Foundation is based in the US, I think this is a way avoid problems with the US government. Contributions are still accepted, but there is need for more more documentation and those ppl. can't be mentioned in the MAINTAINERS file. In the future the should switch their location to another country, where such compromise is not needed.

BUT! If you want read something pathetic, give Linus a try. So after he talked about being Finnish, not supporting russian aggression (This was never the topic) and everyone is a russian troll, he gets few Questions regarding transparency and that this was the only problem with it.

So Linus Torvalds, an important figure in the world of IT - where only good things can come from continuing to do something he has a talent for - made the mistake of talking about something he has no talent for, but combined it with his appalling attitude. He simply accuses anyone who questions this decision of being a paid actor:

I'm also not going to start discussing legal issues with random internet people who I seriously suspect are paid actors and/or have been riled up by them.

By questioning this decision I mean: Asking for better transparency. Never forget: A person can be a genius in a specific field, but an idiot in anything else.
