Germany requires e.Vs to have democratic governance as a response / reaction to what happened during WW2, where every organization was retooled to run under "Führerprinzip" aka, one person decides everything, zero democracy or accountability. Reconstruction decided this was really fucking bad, and made all organizations required to be the polar opposite
I am, and I'm sure there are rules for non-profits in the US that are just as tedious! Like I said in a different comment, I didn't realize Codeberg had a whole German non-profit thing behind it.
I have German background, so that was a genuine concern for me when I started using Codeberg 3 years ago. It's not a great surprise that they end up being more interested in rulemaking around FOSS hosting than in FOSS hosting itself.
