I think there is a distinction. It’s not a ‘nazi instance’, it’s an instance with a couple of nazis using it and tolerated by it. The site ideology is best characterized as “US Libertarian”, the point being that the admin isn’t a Nazi, and their “pro-[personal] freedom” beliefs don’t conflict with the software project and its goal, even if they conflict with me. They can constructively collaborate for mutual benefit. We both hate “big tech” and want an alternative.

A ‘Nazi instance’ and/or a ‘pedophile instance’ is a grayer area cut off, as their goals are more antagonistic and promoting harm by nature rather than incidentally. That’s where I see the benefits of collaboration less worth it and would have no issue rejecting them. And I recall the admins here saying something a little similar, that fascist instances wouldn’t be advertized there.

It isn’t a comfortable decision, but I am able to put aside ideals to work against a massive common enemy. When I read “workers of the world, unite”, I realize it didn’t say “workers who I like, unite”. If a liberal or a US libertarian wants to join an environmental protest or action, good. If collaboration is a pragmatically effective way towards improving conditions and reaching goals, my idealism of purity isn’t helpful. Small FOSS projects need all the help they can get against a multi-national capitalist-funded website worth multiple billion dollars.
