The fact that Twitter, Before Failson, demanded you give them a phone number so they could send you a 2FA security SMS (and sell your number to marketing bullshit, probably) or your account couldn't be verified as A Real Person... and Failson has now apparently decided "SMS 2FA is only for Twitter Paypigs, disable it by next month or we'll kill your account" is so fucking sad and pathetic it loops back to being hilarious.
