In a statement, a Twitter spokesperson told CNN that security and privacy are both longtime priorities for the company. According to the disclosure, Agrawal and his lieutenants repeatedly discouraged Zatko from providing a full accounting of Twitter's security problems to the company's board of directors. Zatko believes his firing was in retaliation for his sounding the alarm about the company's security problems. But Twitter's security concerns had come to light prior to 2020. Twitter says that it allows bots on its platform, but its rules prohibit those that engage in spam or platform manipulation.
