Kissner's departure reportedly coincided with the resignations of multiple other top Twitter leaders Wednesday evening over fears about the company's legal exposure before the Federal Trade Commission, according to an internal Slack message viewed by CNN. The independent journalist Casey Newton and The Verge first reported the resignations.
The employee's post also claimed Musk's focus on monetizing the platform could jeopardize vulnerable users including human rights activists and political dissidents. The employee claimed to have overheard Alex Spiro, Musk's attorney and, according to the message, Twitter's new head of legal, saying "Elon puts rockets into space, he's not afraid of the FTC."
Twitter has twice settled with that agency over user privacy violations, and faces whistleblower allegations from its former head of security, Peiter "Mudge" Zatko, that the company under former CEO Parag Agrawal had violated its FTC obligations a third time. If proven true, Zatko's allegations could result in billions of dollars in fines and personal liability for Agrawal.
