No, I chose the word I chose.The word you're looking for is centralised authority
"Dictator" is like "propaganda"- the words were originally neutral. Just because other people have internalized liberal democratic thinking and they believe a "dictator" is inherently a bad thing doesn't mean I have the same viewpoint.
Besides- a centralized authority could mean for example rule by the Communist party... or the Democrats, for example. That is basically like YouTube- a dictatorship by elitist liberals. I mean a dictatorship by a single person not by some vague "central authority". An unspecified "central authority" could be rule by a Communist party or a cabal of smug liberals working behind the scenes at YouTube.
