@cafkafk >what free software are you writing
Plenty really, I have a fairly large cgit repo.

>how much money do you give to the FSF
That's not important, but I am a member.

>what are some actions you are taking to promote free and open source software?
I'm focusing on eliminating "open source", as that just leads to proprietary software: https://www.gnu.org/philosophy/open-source-misses-the-point.html

I also sometimes look into {L}GPL violations and document the violations so the copyright holder can get in there and ensure freedom.
