I don't think so. Bitcoin is not illegal and its current direction is getting adopted by large institutions. They can easily lobby against this kind of measures if it's the case.
Honestly, I don't think institutional investors are that interested in bitcoin being censorship-resistant or private, they rather value the "store-of-wealth" aspect of bitcoin that allows them sort of hedge against money printing. If some platforms or persons get banned for doing bitcoin, it is not a big deal as long as bitcoin works and produces new blocks.
That's correct. But they will care to know Bitcoin maintains (or grows) its price, and that cannot happen if it's unmaintained, or if people are panicking that the devs cannot access the source code.
Although I understand very well why the vast majority don't want to run a server, I tend to believe that our devs are not like the average Joe, nor like the average software developer. Also I think that some reputed entity will step up and say "hey, we've deployed this repository for you to use", in a somewhat similar way the whitepaper got "adopted" on many websites (I know that it's not that much similarity between the two, still...)
