Arron Banks (rich, arrogant backer of Leave.EU) sued Carole Cadwalladr, the Guardian investigative journalist, for libel, for a somewhat vague quip she made about him in a 15-minute TED talk.
It dragged on for years (at huge cost), apparently designed to ruin and silence Cadwalladr. But the judge finally ruled in Cadwalladr's favour, on the basis of public interest (Cadwalladr kicked off the whole investigation into Facebook, Cambridge Analytica and illegal funding of Brexit campaigns).
Many celebs whine about being "censored" on certain social media platforms, but when the ultra-rich go after you with expensive, often fairly frivolous, lawsuits designed to break you, that seems like the real threat to free speech.

Here's the video of the TED talk in question. The bit at the beginning about a working-class region in Wales that was very pro-Brexit, despite massive funding it had received from the EU is interesting - the weird, targeted fearmongering anti-EU Facebook ads bombarding people in that community, etc.
