There's lots of changes to society that I think would be good, but "ability for government to decide to spend taxpayer money on a charity like Wikipedia, or to create their own version in-house" isn't exactly lacking from the current system.
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 ?
That's generally been very unpalatable to the people who write wikipedia. Even the mere rumour of something like that being considered resulted in a fork of the spanish wikipedia into Enciclopedia Libre back in 2002.
