Everyone is applauding this because they hate Trump, but take a step back and see the bigger picture. This could backfire in serious ways, and it plays to Trump's base's narrative that the mainstream media and tech giants are colluding to silence conservatives (and maybe there could even be some truth to that.) I know the Valley is an echo chamber, so obviously no one is going to ever realize this.
Remember that Twitter gets something like 500 million tweets per day. If it took someone working minimum wage 15 seconds to decide whether or not a tweet violates their ToS, Twitter would spend 30 million dollars a day on this, and the results probably wouldn't even be that good. So they don't do that, instead focusing resources where they will have the most impact.
I am also pretty sure they are not trying to censor conservative viewpoints. If Joe Biden starts telling people to go shoot looters or that Mitch McConnell murdered one of his aides, I am sure they will add a little note to those tweets.
