Their websites states, "University of Michigan Mott Children's is the only children's hospital in Michigan ranked nationally in all 10 specialties." I can't discern why they are "not a charity," which means prospective developers probably can't, either. What this signals is a huge vulnerability if you attempt to partner with anyone, ever, and release a charity bundle, and only later find out that run-of-the-mill fundraising causes are "not charities."
Also, setting aside certain controversies about Planned Parenthood aside, it's bizarre to label them a "political group." They are a non-profit that provides actual services and education. That would be like calling 7-11 a political group that promotes Doritos.
So, I find all of this deeply confusing and unsettling. I don't see how Unity could be viewed as a trustworthy partner by any dev or publisher. You could be on the hook for tends, hundreds of thousands of dollars for donating a game. This seems to make their promise not to charge charity projects a lie. There was no indication any sort of litmus test would apply. They didn't say "charities we like well enough," they said charities, and this odd behavior doesn't seem to provide any sort of reliable working definition of what that might be.
