The possible new owner of Twitter is wasting no time going after his competition in social media, including Truth Social owner and former President Donald Trump.

Elon Musk has been very wrapped up in Twitter as of late. The entrepreneur recently bought the social media company for a whopping $44 billion, CNN reports, taking the once publicly-traded company private.

What Musk’s takeover could mean has many people worried. Internal Slack messages obtained by The Wall Street Journal show just how worried Twitter employees are about what this means for their future. Vijaya Gadde, Twitter’s head of legal, did her best to comfort employees, telling them: “Letting this cycle pass and focusing on the important work we do everyday is the best path forward.”

Gadde’s team is responsible for writing and enforcing the company’s policies, including decisions about account suspensions. According to The Wall Street Journal, during Gadde’s decade at Twitter, she and other Twitter executives have been escorted by armed security on more than one occasion due to threats of retaliation against rule enforcement.

Her team’s biggest concern is Musk’s broad definition of acceptable speech and what it could mean for what’s allowed back on the platform.

Based on Musk’s tweets on Wednesday, it appears Twitter employees have every right to be worried about the future of the social media company.

One thing they might not have to worry about now, though, is former president Donald Trump’s return to the platform.
