I think most will. The idea is that it is a lot easier to do it via fear, but it requires constant upkeep (you have to go around occasionally reminding people why they rightfully fear you). And as it is troublesome to switch one for the other, many people will conquer via fear and then get stuck with it.
As long as you
can rule by fear. BTO's are a pain in the ass right now because it's almost always worth it to take the region nicely to cut down on rebuilding time, and because there's no possible way to have a region kept in check by, for instance, hanging rebels and still have anything resembling good production.
