TTRPGs for Reproductive Rights bundle on Itch, benefitting abortion rights charities. Has a lot of cool stuff, well worth your $5.00 minimum purchase.
(Overlaps somewhat with the comparable Drivethru bundle, but this also has a lot of things that one doesn't. and a lower minimum price, if the Drivethru one was too expensive for you or something.)
A Mastodon server for RPG folks to hang out and talk. Not owned by a billionaire.
