Lol, bro, my incapability or your lack of clear communcation? Modifying a quote of my comment is about as obtuse as you can get.
GNUSocial had an XMPP plugin, it was not built on Jabber. Yes XMPP clients have microblogging built out, but still lack some competitive features to the Fediverse, and fundamentally are still a server-based ecosystem rather than a self-hosted p2p ecosystem for persistent content which is what my post was discussing.
Thanks for clarifying, I figured fashion had at least something to do with it given the number of actively used protocols and services that still use it, XMPP being the one I use the most myself.
Even on XMPP I have seen several projects to “translate” the protocol into other languages (specifically Rust in one).
Efficiency makes sense, but then also the number of devs proficient in a language due to shifts in the emphasis of training and education is just as strong a force.
