Do you donate to Wikipedia?

They, like most western institutions, don't accept any currency I have access to nor any payment medium I can use.

So, no.

Would I?

Yes. Every time I see some political/corporate whack job take potshots at Wikipedia with threats or with calls to brigade it, I would give up something in my monthly mad money spending and put it on Wikipedia. It's not a perfect institution by a long shot, but it's faaaaaaaaaaaaaaaaaaaaaaaaar better than any institution filled with political whack jobs.
