Because it was the moment Twitter decisively shifted from an open fair neutral public forum, where contributor accounts could be neutrally & objectively confirmed to be who they claimed to be, to a biased forum which refused legitimate identification of anyone not in line with certain sociopolitical views.

Anonymity is important, and Twitter gave that to anyone who wanted it. Identification is important too, and Twitter denied that to dissenting views (not weirdos, but about half the population - normal mainline opinions).

Twitter isn’t grade school. It succeeded as the new global online public town square, widely quoted as an authoritative forum. If @Talanes posts something important, good to know it’s the real Talanes people assume it is - but if he’s denied a blue check because he promotes wrongthink (even if shared by hundreds of millions), the validity of the post is questioned.

I’ve seen enough “not really who you think it is” accounts obfuscate truth to know it’s a real problem. Online identity verification, when wanted, is important.
