there are many issues around social media that are still unresolved and existing fediverse implementations are not necessarily more advanced in this respect.
but the transparency, evolvability, standards based architecture are all aspects that would much accelerate finding solutions
its a good read but remarkably it manages not to mention once the fediverse (and mastodon in particular) where alternate strategies are already facing empirical validation.
if they did do a more thorough research of how it is setup they would know that some very simple choices have huge calming effect: e.g., not showing the number of "likes" on the timeline and not allowing "comments" on reposts. and those are just tiny interventions in the scheme of things. having open source codebases that can be forked but still interoperate via activity pub means that a fragmentation, speciation, niche creation will happen organically which will further reduce the phenomenon of irrate digital mobs
its not like people don't have imagination, but a "system" that sucks in XX billions of profit per quarter acts as a black hole: any light-ray of hope is crushed back into its reality distortion field
