Do you consider mute lists to be “censorship”? I don’t, and I’m guessing you don’t either. In which case: why do you consider the WoT scores on Amethyst to fit into the censorship category?
I’d argue it’s censorship if it’s centralized, based on global trust scores. And yes, Bluesky is centralized. But if the system is personalized, like a mute list that you manage yourself or the metrics on Amethyst that are personalized to the end user, then no, it’s not censorship.
I should probably point out that the scores on amethyst are calculated using open source software that you can run yourself. You can delegate the calculations to someone else if you wish, but it’s not necessary.
