For the record I like Mastodon a lot and think it's a fantastic project. It's doing something the internet needs, which is decentralized, federated, non-corporate social media networks.
These criticisms come from a place of personal interest and intellectual curiosity -- it's not a hit piece, it's a critical one.
@crushv Actually, I'm interested in writing about Pleroma (as well as federated social networking in general). But for this piece I was much more interested in Mastodon's history and some of the criticisms levied against it by users who left or consider leaving the platform.
