I think this move by Twitter isn’t part of some bigger policy (or if it is, then it is surely just the start.) There are plenty of (worse?) examples that Twitter and Facebook essentially ignored or (maybe mostly Facebook) amplified like in Sri Lanka or Myanmar.
I view this ban as a result of internal politics at Twitter as more people have sided with those employees who don’t like trump (er, basically all of them) and want to replay form him. Maybe I’m wrong and it’s really motivated by self interest given fear of some legislation other than a defence spending bill being passed, but it makes me feel better to imagine that these decisions are the result of careful moral thought and ethical considerations rather than some political calculation or CEO’s journey of self discovery

Yet, Twitter, FB, and YT are quick to censor MEMRI and PalWatch, which actively report on vile speeches around the Arab and Muslim world about how Jews are descended from pigs and dogs, etc., the Holocaust was a hoax, on and on. Because "hate speech". Memri in particular, a non-profit translation service, had hundreds of its videos taken down, footage of these speeches and broadcasts, a valuable resource chopped off for political correctness.
In the early-to-mid 20th century, the phrase politically correct was used to describe strict adherence to a range of ideological orthodoxies within politics. In 1934, the New York Times reported that Nazi Germany was granting reporting permits "only to pure 'Aryans' whose opinions are politically correct". [0]
