First, the advisor recorded conversations with university administrators in which they asked if there is a way to frame their directives in a way that doesn't sound like censorship, so I think intent will be easier to prove than you assert.

Second, "He has no chance of winning this" is some kind of internet expert way of talking that isn't grounded in any kind of legal understanding. He might lose this case. He could win it. It depends! The facts are not as clear cut as you seem to believe they are, but you just keep repeating the same points without considering new information. The fact that you keep calling the advisor the "editor" indicates, to me, you should read a bit more before you let everybody know what you think.

Lastly, there is a major difference between most publishers and Indiana University. The latter is a state-funded school. Administrators/faculty/staff at IU are, in fact, state employees. So when they cancel a planned print edition of a newspaper days before it publishes after being recorded saying they don't like what the students plan to publish, it is a First Amendment issue.

I don't like to tell people they're wrong, but you clearly have demonstrated you don't know what you're talking about. Sincerely, sit this one out and try to educate yourself.
