However protesters and government being in agreement does squash your silly suggestion that its part of some government conspiracy heading towards dictatorship.
It doesn't matter why these people tried to demonstrate. They wanted to be on the streets making their political views known and the government suppressed their rights to political speech. Suppressing demonstrations, protests, whatever you want to call them is a path that every dictatorship has gone down.
Frankly, I cannot believe how naive and childish you are in thinking that just because the protesters may have agreed in some small way with government policy means that suppressing the protest was the action of a government that is interested in freedom of speech.
