under Web of Trust, the people you follow are the main signal by which your client filters. So if you follow people who have muted me, you are going to end up not seeing my posts in some context. This carries over to extra layers in some implementations, which means not only the people you follow can influence the censorship algorithm, but the people that your followers follow as well. While Web of Trust was a good idea, unfortunately there are already people abusing it for censorship purposes. The designers of WoT imagined that people would be using it to report spam. But the reality is that there are now popular accounts running around muting people for political reasons, in hopes that nobody will see their posts.
