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.
No, it would not, because generally left-wing people don't spread lies with the intention to dissuade people from voting (quite to the contrary, the left wing is fighting for people to have the right and means to vote) or call for storming the White House and start shooting.
If you believe your side is the good one and the other is bad, it's probably because it's part of your identity. And that prevents you from thinking about it honestly and results in more polarization. Once you accept they're all full of it, you will think more clearly. And you'll have better dialogue with opposing viewpoints.
