Well that's clearly false, if it didn't matter and was just a website then why is there so much drama over this, why are prominent journalists covering it, why is this thread nearly at 300 pages?
Twitter does matter, it has an outsized influence on discourse, it's used by activists, it's been manipulated by fringe groups, state actors etc. it played a huge part in the Arab spring. To claim it doesn't matter and is just a website is incredibly naive.
That's clearly false too, just look at the text messages from the court docs posted earlier, free speech was a big factor in motivating this takeover.
