Are you talking Twitter or X? X is in many ways much closer to TruthSocial than any other platform currently is [1] [2]. The only thing that grounds X a bit is the (old) Twitter user base that’s still on there, which is and has been declining.
It’s also interesting that your view of progressive might be different than mine. In this current age, I guess even advocates for DEI are considered too “progressive”. Which (in my opinion) relates more to a shift of right to far right, which shifts the balance, and people mistake it for what are really just centric viewpoints being “leftist”.
To me, BlueSky is the best current alternative to what Twitter originally was.
