Many examples there, like: "From 2019 to this year, Harvard sanctioned four scholars, three of whom it terminated." or "In 2020, Harvard revoked conservative student activist Kyle Kashuv’s acceptance over comments he made on social media as a 16-year-old, for which he had since apologized. "
Some other colleges as well:

The survey results are interesting, but I think contradict the point you're trying to make in many cases. For example, the survey showed students felt less comfortable discussing abortion. An odd result if the claim is there's some kind of liberal oligarchy that's selectively punishing conservative speech.
CogitoCogito asked for "specific examples of the universities in question acting in contradiction to these statements". When you are providing specific examples, a handful are enough.
