No. The Ministry of Truth and the protagonist of 1984, it’s employee, were engaged in revising the written record to make it match what the Party wanted in the present. They were also the only source of information. Twitter is not doing the former and isn’t the latter, so equating it with Minitrue is 100% factually incorrect.
Sure not everything matches up. The Ministry of Truth was government, but in America the same type of group exists and it's private. They don't have to rewrite history. They're rewriting the present.
That’s typically referred to, at its most specific: fact checking, less specifically: news reporting, and most generally: making a claim of fact... when one disagrees with the check, report, or claim.
