Everything that president said and did was covered by the press around the world, an army of spokespeople and a million online sycophants. He isn't (and certainly wasn't) "stifled" by the banning of his social media accounts. Really, tech companies bent over backwards to accommodate him, gave him far more slack than they would give you or I. And even then he had to cross the line twice.
Hell, he's still the frontrunner for the Republicans in 2024, and the last anyone heard from him was that he was selling NFTs.
The narrative of Trump being silenced by big tech isn't working, find another one already.
