Oh yes, there was a lot of outcry against the Empress (old-Seph for example considered her an usurper for not following the proper channels to reach the Throne), but with time, the Empire is the Empress, so you need to accept it and follow/obey. Like it happened during the times of the Mad Emperor, it's not the place of those without certain powers to judge those above their station. You may like her or not, but you should certainly not speak against her, or else the MIO might pay a visit in the night...
