Why are the West Bank and the Gaza Strip considered to be dictatorships?

Both have authoritarian leaders whose hold on power is not subject to election. Hamas rules the Gaza Strip as a combination between a military junta and a theocracy, both forms of Dictatorship. The Palestinian Authority rules the West Bank as an illiberal democracy with suspended voting, which is another form of dictatorship. (The Israeli-held parts of the West Bank, aside from East Jerusalem, are ruled under martial law, which is effectively another form of dictatorship.)
