Looks like Motherboard did a write-up of the #tMobileAt fiasco from last night: https://motherboard.vice.com/en_us/article/7xdeby/t-mobile-stores-part-of-customers-passwords-in-plaintext-says-it-has-amazingly-good-security
Best part:
"A T-Mobile Austria representative said that "there is a misunderstanding in this thread about how we store and what is being displayed for customer service agents. I will check with our security officer and get back to you." But didn't immediately follow-up."
Looks like full damage control mode to me.
