Ive seen that pixelfed and peertube have the ability to add a licence to content. I think this would be great for everyone so we can get ahead of threads and have collective bargaining power when they inevitable put our content between ads.
Heres the pixelfed duscyssion on the issue: https://github.com/pixelfed/pixelfed/issues/13 Here is mastadons discussion: https://github.com/mastodon/mastodon/issues/20079
Im not sure if lemmy has a discussion yet i may create one later if one doesnt already exist.
Im sure they will just totally ignore licencing but in the long term its going to give us a lot of collective bargaining power when it comes to corporations tryung to prifit from the fedivsere.
My ideal implementation would be each post has a licence decided by the poster and each instance has a default. In that case if u wanna post with a free for anyone to do anything go ahead its your choice.
The only privacy the fediverse provides is through anonymity i doubt licencing would effect that at all. But llm training it could force a lot more opensource into this world.
