I am drawn more and more towards simply "communal software". It is simple and to the point without needing to bring in a lot of loaded political baggage. Sure capitalists might fund some of it, but I think it would be significantly more difficult for capitalists to co-opt "communal software" than the nebulous "open source" which has had its meaning intentionally diluted and stretched to absurdity.
I had an interesting conversation about how "communal software" would be best translated into Spanish. I learned that "communal" in Spanish has connotations of helping, somewhat like "charity" or "welfare" in English. My friends suggested "software cooperativo" instead.
That got me thinking about using "cooperative software" in English too. I think I like it better than "communal software". "Cooperative software" feels more inviting to participate. If you don't consider yourself part of a community, "communal software" may not seem as inviting, as you may think it is for other people. What do you think?
