He's very exercised that the new X terms of service call for any lawsuits involving X to be brought in a local court in Texas (X moved there). This is a standard thing companies do but which the highly-informed Don LeMon thinks is an innovation that Elon Musk just came up with.

He was also upset that X is no longer the place for honest debates, which is the left's way of saying they're upset that it does allow for honest debates. They want rigged debates, where dissenters are either banned outright or forbidden to make their arguments.

Because he didn't get the engagement she was looking for, Don LeMon then posted a formal written Notice of Intent to Leave X.
