Anti-censorship has always been the #1 benefit of federation and peer-to-peer connectivity. I don't think any other benefits come even close, and they are usually overshadowed by how much more difficult it is to build a well-working federated or P2P network.

But when you start having global monopolies in various industries that don't care about automatically banning the "little guy" from which they make little money to begin with and when you have governments that are increasingly more interested in let's say "curating" the internet, then that anti-censorship benefit starts to become a lot more appealing to a lot more people.

It's why I'm glad Firefox is not only finally a decent competitor to Chrome but also starting to adopt all sort of anti-censorship protocols and technologies, too (and hopefully there are more to come).
