I agree with what your saying in general, but this isn't really an instance of someone being taken down. I read it like when one of us normal folks deletes our social media accounts for mental health. Twitter seems like a toxic environment, but it didn't silence him any more than getting sick of the constant weird reality distortion on facebook made me delete mine. It just got toxic enough for him to decide to shut up.

The distinction matters because sometimes people not aligned with the zeitgeist do face serious consequences like being fired, receiving violent threats, etc.
