Not a traditional license, but this project has explicit political goals: https://code.tesio.it/p/self-hosting/doh.cgi/file?name=POLITICS.txt&ci=tip
It doesn't need to enforce them: anyone using the software structurally contribute to the goal unless you run it on #BigTech servers (but that would be a pointless waste of money).
The #HackingLicense it adopts has a few political goals too, but more subtle.
