Discovered this morning that Maven https://heymaven.com (a social media startup who's CEO is ex OpenAI "Ken Stanley: leading the Open-Endedness Team at OpenAI") is mass importing public posts from the #fediverse with no links back to the original and no way to delete them. It seems there is no Opt-out or Opt-in mechanism at all. It also has posts from #Bluesky pulled in via @bsky.brid.gy@bsky.brid.gy that are also not linked back to the original.
UI differences are a big factor in the success/failure of decentralised federation of diverse platforms and content
And this seems a good example: bridged #mastodon posts onto #BlueSky which has a lower character limit than Mastodon.
So, just like #lemmy posts on mastodon, you don't get the full content of the post (which ends with an abrupt ellipsis here) and have to take a link to the original platform.
However powerful the underlying protocols, this isn't far from screenshots.
