The silencing of Trump has highlighted the authoritarian power of tech giants | John Naughton

The US president's ban has sparked a furious debate about online opinion, but it's part of a bigger conversation

It was eerily quiet on social media last week. That's because Trump and his cultists had been deplatformed". By banning him, Twitter effectively took away the megaphone he's been masterfully deploying since he ran for president. The shock of the 6 January assault on the Capitol was seismic enough to convince even Mark Zuckerberg that the plug finally had to be pulled. And so it was, even to the point of Amazon Web Services terminating the hosting of Parler, a Twitter alternative for alt-right extremists.

The deafening silence that followed these measures was, however, offset by an explosion of commentary about their implications for freedom, democracy and the future of civilisation as we know it.

But what came to mind continually was H L Mencken's astute insight that for every complex problem there is an answer that is clear, simple and wrong". The air was filled with people touting such answers.
