There are more aspects to evolution. When I use the word, it is from the full scope and against the principles of SX methodology I am working on, which holistically considers the entirety of the ecosystem as a whole.
The fediverse ecosystem evolved to have most day to day conversation on microblog channels.
But if those are ephemeral and fleety, fragmented, where before the discussions on more cohesive commucation hubs that kept an archive of what was said in one place, from that perspective and measured against power that is now lost, one may conclude devolution to place in hindsight.
