Their points about it not having monetization make zero sense - there’s a bunch of shit on the internet available for free, the fediverse didn’t invent that.

It has to be paid for, though. Servers, traffic and disk space aren’t free, the volunteers who run instances will need to be compensated once their instances start to become their day jobs and there are legal hoops that some servers will need to jump through when it comes to nsfw content, removing copyrighted content etc. We’re in the early days of the fediverse atm, so it’s interesting to see how this will all pan out!
