Are there any copyleft/open source projects that you would recommend contributing to? Are there any projects that directly support leftist causes/goals? (Ex: Housing, Climate Change, Prison Abolition, Unions/Co-ops, Anti-🧊, Mutual Aid, etc.) This is not an exhaustive list at all.
Ask your local political party (or union) and volunteer for tech stuff for them.
Ask what they use, contribute to that. Or if they use something bad, suggest something good to them, then work on that.
All of those organizations are well known to use a Fascist software stack of closed source enshittified products.
it’s alarming how little this seem to know and i know that i’m not the right one to teach them.
