The article is nice, but I'm not sure if I'd send it to friends that aren't familiar with the fediverse. It seems to gloss over some problems and focus less relevant ones
It doesn't touch on the issues with Blueskys protocol and makes it sound like an equivalent choice (or worse, a better choice). In the downsides section it touches on racism in badly moderated instances, and the difficulty of setting up an instance. Those issues aren't relevant to the vast majority of users who will join a large instance that has defederated from the bad stuff.
It's a nice article for those who are already somewhat familiar, but a bad first impression
