The unsuspended journalist accounts returning to Twitter to continue to maintain the value of that platform for a megalomaniacal fascist who hates them and everyone like them and will do worse things is… something.
I think any journalist who operates in an environment where they concede that they could be banned at any moment is succumbing to a form of voluntary censorship. I experienced this in South Africa, as others did I am sure and remember the idea of 'banning'.
Having experienced this I assure you it's not the mark of a 'free speech' environment.
