While I don't really approve defacement, that was not the point in my comment. If the defacement would have been done to DOJ (or whatever front the prosecutors have) website, I might have disapproved but still at least I would have found the target appropriate.
As you self say, it is the government that was "overstepping the mark". Attack them instead of MIT which was pretty much the least evil party in the whole case best to my knowledge.
That's a good citizen.
Back to work with you.
