StackOverflow seems to handle the fine line well, Reddit as well. They both provide volunteer-heavy knowledge sharing while not appealing to charitable emotions that are disingenuous (if wiki is dying, fine: say it, but if it's not then their only way of growing budget is to pretend it is - it's the sign of an issue for me)
Communist revolutions are just anger and frustration making heads roll all around for a big reset, but the phoenix rising in the ashes of the revolution surprisingly often has the same face as it had before. I live in China, my friends always tell me "we've always had an emperor in Beijing, this is the same thing with another name, why make such a fuss about it", proving that not only did the revolution change nothing for them, but worst: they don't even see there was some sort of point to it. So a communist revolution will change nothing to Wikipedia's governance.
I don't think Wikipedia can be state-sponsored, or even UN-sponsored: it doesn't matter enough. But a corporate entity with a product vision and a clear statement of profit would reduce the tearful aspect of their marketing campaign, appeal to its utility rather than our sobbing hearts and maybe shed a bit (a lot?) of the volunteering to welcome people like me who edit wiki for stuff they need rather than to "offer the world a knowledge sharing platform" in itself ?
