As do lots of people. And lots of people liked "dragon" for car, "small" for child and "farspeaker" for telephone. People in other kingdoms still use "eric" for list field.
Autocrat is a perfectly period word, but NOT in the way we use it. Should we not try and use terms that are closer to what our period contemporaries might have used? I am firmly in the "gate" over "troll" camp (which is why I made the sign for coronation), and I don't like using <job description here>-o-crat at all.
But to prove I am not completely above hypocrisy, I still favor "mundane" over "modern", despite the BoD's wishes.
