So are whistleblowers like Deep Throat ate people you believe shouldn't have right to report and publish material?
> When I think of free speech the context is usually the freedom of discourse and the ability to say controversial things - rather than the demand for total and unrestricted liberty.
You have it backwards. Your pursuing permission not freedom. To have the freedom to speak of controversial subjects speech you must first have the freedom to speak. Freedoms are unrestricted by their very nature.
While I'm not very knowledgeable of English Law, Cambridge University (and every other university in England) receives taxpayer funding. If keeping free speech on campus is a condition for such funding, then this isn't censorship, but a contractual matter between Cambridge and the English courts that Free Speech Union would like to have observed and enforced.
