An action the payment companies took extrajudicially at the behest of the US government because the US gov was't happy with Wikileaks. Wikileaks' crime was that they'd been very successful at getting true information to the public about what governments were doing.
This was quite shocking to me (and at least some others, presumably) at the time, in 2011. I guess if we were taking it seriously, we would have been obliged to say: oh, how fundamentally authoritarian and anti-democratic.
When progressives/democrat/left types shout "fascism!" now on account of something Trump did or said, the cynical part of me says that a lot of them probably just want Obama/Clinton/Biden-flavoured authoritarianism rather than "ugly" lower-middle-class Trumpian authoritarianism.
