Lots of ways to foster a healthy software commons without supporting the FSF.
An easy one: caffeinate some #OpenSource developers whose approach you appreciate. If that's me, try https://github.com/sponsors/schmonz
Or if you'd like to contribute together, join me: https://pubmob.com/offerings/amitaischleier-legacy-open-source-fridays/
Wondering what you'd be supporting? My GitHub Sponsors page (https://github.com/sponsors/schmonz) gives a high-level overview.
Also, at the end of each month I summarize my efforts. For example, here's December's post: https://www.patreon.com/posts/december-news-45650445
