Yeah, I think they wanted to have have the story die pretty much and no one wanted to visit or draw any attention to the problem - that is, until Trump decided to visit - it seems straight after he said he was going to visit then the EPA, Governor, went there pretty quickly to beat him - unless even that was part of the theatre - about Twitter banning posts - yeah most likely, who knows - I would say these days they use some kind of new shadow ban - I know in the past few months the censorship seems to have come back in a lot of ways - still not as bad as it was before, although given what we know now, that is not saying much - before it was like a endless stream of press releases from the US State department.
Thanks!
