I might say that anything relating to content would be a prime benefactor of decentralization. If you wish to control your own data be it cat pictures, a video channel, streams, email, website, payment method or whatever then the only sure way to prevent other people's ideas, ideals or ideology from affecting your data is to not cede authority over it to anything or anyone.

For an oversimplified example I could, in theory, be in control of my input on this site with a nifty membership hook for publishing (or revoking) my interactions with it by working in my own "shared" instance of HN using a mutually agreed upon distribution protocol wherein each comment is published and "owned" by the commenter without HN having to pony up the resources to store or display it. Which could possibly include some potential for eliminating "acceptance critereon" altogether. ie. HN would have to ask me directly to manipulate my input for anything other than ranking or basic community acceptance. Wherein, ultimately, HN could pull the plug whenever but my "shared" instance could live on with others' until I, alone, pull my own plug which could even result in "comment deleted" throughout all live instances for all prior comments. And so on.
