I don't think this is an explanation for the current status and gains of Twitter. Trump has been president for over a year, and has been a prolific tweeter for far longer. If anything, Trump tweets are less novel and more common place then they've been to date.

I think the activity on twitter being referred to is about Trump's presidency, not (mainly) about Trump's tweets. Same reason why cable news is raking it in.
