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.
It can’t be all perfectly achieved, but to do nothing, as they were before, could be now determined to be a worse case than providing these annotations to flagrant misuse by the highest impact profile that they can’t do away with entirely.
...but I think a greater concern we can all agree on, is that for the type of communications that Twitter does - Twitter is effectively a monopoly. The people being censored here can't even themselves go to any alternative platform, because there's really no other platform at that scale for that content format.
...that's a bigger problem, because it gives Twitter the power to shape global communications unilaterally. Something no corporation should have the power to do.
I think, broadly, that censorship should be regulated by democratically elected bodies - not corporations.
Twitter only has about 150 million daily active users. That's 1/3 of the population of the USA. There is no way in hell Twitter could ever be considered a monopoly when less than 2% of the world's population even uses their platform actively.
