The problems are more precise as stated in the article :

Where is my community of people I want to publish and subscribe with ?

Alike Twitter actually losing half of its userbase.

What do I share with whom, do I give out much private information, would I get stalked or banndd, is there moderation, how is gatekeeping done ?

All these points seem taken care of by federations like Mastodon and alike where everyone is free to chose and quit an instance if not adapted.

Even the Twitter split is showing only different platforms for different people endeavours work.

Now from an OSS point of view, Mastodon and alike are complicated to keep track of.
