Not a bad argument in the beginning but there is some how a lack of accuracy further down where it all becomes very hand wavy because the chain of arguments becomes to complex for Twitter-style replies to do a good job.
Fwi saying this after actively engaging with the Fediverse for 2 years. I even home ran my own Mastodon instance for a year. In my opinion the Fediverse is dead. Reason, it’s boring. So I said it :)
Last year at censorship.wtf, I attended a workshop by people who used to run one of the biggest Chinese Mastodon instances. They had a few million users, and it cost them tens of thousands of $ per month to keep it running. But the much bigger problem was that three-letter agencies were reaching out to them to censor some content. Many of these requests came ofc from China, but some were from other countries. And I think this is the downside of the Fediverse system - if you have control over your instance's data and it's not being replicated by others, it also means you can be more easily pressed to censor it.
I'm so biased towards favoring the fediverse. I think it's a wonderful livable architecture that works very well :)
