Maintainers ≠ developers, and it wasn't that long ago when we heard Linus moaning about maintainer shortage and nobody wanting to pick up their work. Now we get this. Whatever you think of this particular decision, it won't help with finding more maintainers, especially from countries other than the US and its closest allies.
I live in a country which may one day find itself under US sanctions, and I'm been busy cutting reliance on American services, just to avoid having to migrate everything in a rush if that happens. Everyone here understands this (for example, my day job migrated off GitHub to self hosted gitlab back in 2022), and I can't imagine many people will be interested in spending years of effort to then possibly be kicked from the project because they chose to be born in a wrong country.
