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.
Unlikely that any of us can answer this question properly unless we happen to know detailed laws for every country in the world. If we want a real answer we can trust then we’d need a statement from someone like the EFF otherwise our “licence” is barely more than one of those chain-letter comments saying “I do not give Facebook the right to do X”.
