Your point in hypocrisy of appeal to Freedom of Speech (cultural, not constitutional) is well-taken, but I would argue it is a red-herring: unless you have studied their intelligence files, it is not at all clear to the general public whether the deportees are merely selected because of a speech concern or some more nefarious intent or association.

Keeping secrets from the public is a good way to lose the public trust which they’ll need to stay in power. Otherwise their replacements will have their own secret reasons to be deporting people.

I’ve already resigned myself to the reality that freedom of speech no longer exists and hasn’t existed for some time. I think only the times when we thought we had freedom of speech was when information was very tightly controlled and the few cranks in the periphery were not a threat to government legitimacy. An increasingly weak and illegitimate government cannot afford to allow free speech.
