US has overwhelmingly all the developers of Fedora. If Fedora wins over all other linux based distros (and at this time it could be easily do in a near future), developers in other countries will move on into other projects (or move to the US). If the US, once Fedora is so clear dominant and Debian and Arch ceased to exists down the road, the US will find it compelling to close source Fedora and leave the rest of the world with a forked version but unable to develop for the time being since there is no Linux experts around left.

this isn’t even possible even if fedora got 99.9999% market share, most linux distros are passion projects, even the ones that aren’t don’t need much funding. Debian will never go away, arch will never go away, so that simply can’t happen unless they’re militaristically destroyed. You say this is not far fetched, but i’m afraid I completely disagree, that doesn’t even sound remotely possible. Fedora doesn’t even do that much, they just package together a bunch of other things that are developed completely independently of them (they don’t even make their own kernel, that’s like 90% of the work!)

fedora cannot legally become closed source, most of it is GPL licensed. Lookup “copyleft”, this is why android isn’t already proprietary.

If Firefox closes, the dudes in librewolf will survive for a few months (I’m in Librewolf), that is it; none of them are capable of keeping developing Gecko (the engine of Firefox). Imagine that Google close sources Android, no one in the world (besides Huawei) could keep develop it competitively for at least a decade!

This isn’t true, there are many open source android projects could easily keep things going. The only reason huawei does all that is because of the proprietary parts, this doesn’t exist as a problem in linux, and cannot be created as one. Firefox would still be developed without mozilla, just significantly slower. Lookup phones with microg, they have no such issues keeping things going. Browsers are a special case that require a ton of resources to keep secure, OS’s, not so much.

Also, google cannot legally close source android, that’s the point of the GPL.

Even then what you’re saying is “these aren’t viable open source projects without a lot of funding” and android absolutely is, firefox MIGHT be.

Look at this… SWIFT (an interbanking payment system) , when US, in spite being European, dominates it completely, Russia and China has been for half a decade create and alternative… it is not a mayor technically difficult platform to replicate, but it is proven very hard… relying on it for decades had left every country at its merci and now that most of the world wants an alternative still could not come up with a viable alternative. Remember also when France/EU wanted to create a payment system with Iran… well, never came to fruition. Haven relying in the US for decades left Europe powerless for these innovations. The same could happen with Fedora if we start adopting it in mass.

none of these concerns resemble this situation.
