Does gethub (or similar) have a banking/donate function?
I don't know of another way to donate besides PayPal.
The PayPal button we used to have, only temporary, was connected to my personal account. And to be honest it worked but I just don't want to deal with (be responsible) for it.
But yup... I would love the dev's and the admin guys to get some money in pockets.
Buy them stuff?
Ask your fav dev what stuff they want from a website ... Amazon etc
Pako is my fav.
