I for one am going through quite a culture shock. I always assumed the nature of FOSS software made it immune to be confined within the policies of nations; I guess if one day the government of USA starts to think that its a security concers for china to use and contribute to core opensource software created by its citizens or based in their boundaries, they might strongarm FOSS communities and projects to make their software exclude them in someway or worse declare GPL software a threat to national security.
I think the prestige of “maintainers” and contributions/control are what is being torn down. Anyone anywhere is still welcome to contribute, they are simply limited from direct control. They can still fork at any time, anyone can. Getting people to follow your fork is another thing entirely, and your open source code will still likely be incorporated directly or indirectly. The only thing that has changed is the misguided prestige that has grown around the project and is not a required or relevant part of the project as a whole.
