I'm sure we all agree that Wikipedia has a ton of biases in all sorts of directions, but I'm not following that Wikimedia has anything to do with. They rarely make any editorial choices, usually only following legal decisions.

Maybe it doesn't, but a commenter further up mentioned wanting both Wikipedia and Wikimedia. So in turn, I'm not following why Wikimedia alone is the focus here.
That said, it seems like a no-brainer that using a hands-off approach in a subculture known for being biased is an open invitation for articles to become biased. That doesn't mean Wikimedia is at fault, either.
