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.
POTUS has the most popular (and currently most controversial - note, that's _controversial_ not _extreme_ or some other morph) so it's easy to see why Twitter are on top of it. Other blue-checked accounts, whilst more "important" than unverified, just simply don't compare to the importance and prevalance of POTUS' account.

It goes on to say this can’t be possible because it would mean that conservative content would have to violate rules at 4x the rate of others, and that statistically its highly improbable. Why? It’s a known problem that Twitter has a lot of accounts that are fake accounts from bad actors trying to sow discord in the US political system, and those tend to be right leaning. Didn’t Twitter relatively recently do a purge of a large number of accounts that were deemed fake? That could easily skew the numbers, especially because those accounts tend to engage in the kind of rhetoric that gets you banned.
And then the article points to cases where liberal leaning content doesn’t get banned even though it should. I can also find cases where conservative content violates the rules yet it didn’t face consequences, most prominently the president’s account. It’s not just liberals who get a free pass, so I’m not sure what that proves.
Is it possible there is a bias in how Twitter sensors content? Sure. But that article makes it sound like they have a data driven, mathematically rigorous proof that it’s true, and I don’t think they meet that mark.
