(For those of us lucky enough to be able to contribute,) a reminder: JPR – https://jackpineradicals.com/donate/ .
A few other of my own personal favorites (my focus being on the informational infrastructures on which progress on so many other issues depends):
ACLU – https://action.aclu.org/give/now?ms_aff=NAT&initms_aff=NAT&ms=web_horiz_nav_hp&initms=web_horiz_nav_hp&ms_chan=web&initms_chan=web
Electronic Frontier Foundation – similar to the ACLU, but specializing in online rights. https://supporters.eff.org/donate/30for30–D
Assange Defense – https://salsa.wiredforchange.com/o/5950/c/10065/p/salsa/donation/common/public/?donate_page_KEY=12042
Craig Murray’s blog – for his detailed reports on Assange’s extradition hearing, among other reasons. https://www.craigmurray.org.uk/
Fight for the Future – also focuses on our tech-based rights using approaches that seem like they might help (as contrasted with, e.g., Demand Progress, which addresses many issues I’m sympathetic to but in ways I consider less effectual, e.g., asking corporate sociopaths to be nicer). https://www.fightforthefuture.org/donate?frequency=monthly
The Internet Archive – preserving online history (you know how certain things have a way of disappearing). https://archive.org/index.php
League of Women Voters – https://salsa.wiredforchange.com/o/5950/c/10065/p/salsa/donation/common/public/?donate_page_KEY=12042
Represent.Us – they have the only remotely plausible plan I’ve seen for reclaiming our government from big $. https://represent.us/join-common-wealth/?source=wp-web-0-20201216-fundraising
Destruction is easy; creation is hard, but more interesting.
