@J12t As I recall the gist of it was that Mastodon made it easier for trolls to target minorities cf Twitter. And when people complained about it they were met with technocratic answers about how it was impossible for technical geek reasons and ignoring people's actual experiences.
I found an article talking about it fastcompany.com/90817452/can-m
But I have to disclaim: these are not my experiences so I'm not the best placed to explain them
