Well first not everyone on the fediverse is opposed to the bridge. I agree that public is public. But there are concerns about moderation being incompatible, it’s normal to voice them.
As for the fediverse destroying the open web for everyone else, I think you’re hyperboling quite a bit, the fediverse has done mountains to make social media more open, probably more than everyone else.
Yeah you're right, I think I did overgeneralise there. I was meaning more of the culture of "Mastodon users"; Mastodon itself has done a lot to help the open Web too.
Though I think "voicing concerns" is a bit of an understatement. I feel really bad for the developer of Bridgy Fed, working on their passion project and just getting caught up in all this heat and harassment.
