Tried to go to Gab while connected to the corporate vpn. Got a message that it is blocked for the following reason: EXTREMISM.

I have yet to see an extremist post on Gab. And yet, the Wikipedia description for the site says, "...known for its far-right userbase. Widely described as a haven for extremists including neo-Nazis, white supremacists, white nationalists, the alt-right, and QAnon conspiracy theorists."

"Widely described." By CNN and Snopes I'm sure.
