Any cursory googling of their finances would show you that they balooned and instead of using said finances to run the website they ask for more millions of dollars to sponsor a bunch of unrelated charities and hire a bunch of executives to manage such use of the funds.

I wish someone would hard-fork it already and stick to a promise of strictly sticking to the core job of operating wikipedia the website, with a small dedicated team.

Plus they don't need any more money, they have enough money to run it for a long long time already and if they keep doing a good job people will keep donating. I don't understand this model of "we need to ensure we survive forever as fast as possible by accumulating a billion dollar endowment". Nonprofits should have ~5-10 years runway max and keep getting donations if they keep doing a good job. I don't trust any organization forever. What incentive do they have to be useful and welcoming if they have a forever endowment?
