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.

The Vox piece isn't an "admission" that their moderation is biased. Twitter's CEO is "admitting" that the politics of the developers is heavily liberal:
> “We have a lot of conservative-leaning folks in the company as well, and to be honest, they don’t feel safe to express their opinions at the company,” Dorsey said. “They do feel silenced by just the general swirl of what they perceive to be the broader percentage of leanings within the company, and I don’t think that’s fair or right.”
