Seems like just another reason why defederation should be completely removed from the protocol. It's way too easy to abuse and force centralisation.
There are other far less destructive and abusable ways of dealing with spam and content moderation.
I maintain that it's better to give the users the control, and allow them to decide which instances, communities, and users they want to be exposed to. Bottom up moderation, instead of top down.
For example, instances can provide suggested 'block' lists (much like how an ad blocker works) and users can decide whether or not to apply those lists at their own discretion.
By forcing federation, the network stays decentralized. Maintaining community blacklists that can be turned on or off by the individual user protects against heavy handed moderation and censorship, whilst also protecting users from being exposed to undesirable content.
Google is an ad company. To them, a web browser is nothing more than a tool for collecting user data and delivering ads.
When you use a chromium based browser you are allowing google, an ad company, to decide what the future of web browsing should look like. And this is the result.
Firefox is the ONLY browser which is genuinely competing with google. Do you think ad and tracking blockers are going to get better or worse once they die out, and literally every major browser is running on chromium?
Use firefox and u-block origin. Enjoy a superior, ad free, browsing experience, and support the future of an open web.
