@profcarroll Bridging content to Bluesky without consent violates users copyright to their content because Bluesky extracts a broad license to all content posted on their platform and transfered over their protocol. Bridge builders do not have the right to grant these wholesale licenses, so any such bridge is illegal. Just because you can technically do something does not make it legal or ethical.
@profcarroll Such bridges also violate Bluesky ToS which requires the poster to assert they have the legal right to post the content, since they don't.
@profcarroll When you sign up for #Bluesky, #Twitter or #Meta you agree to give them a license to content you post. It is a very broad perpetual license giving them lots of rights to your content, including the right to sublicense. When you sign up for Mastodon, most instances do not take a license, the content rights you give them are defined in the privacy policy, and they do not include reposting your content to corporate sites that assume licenses to the content.
