You can make exactly the same criticism about free speech to all societies of the early 19th century, except perhaps UK - but not Ireland.
How many free newspapers in St Petersbourg or Vienna or Dublin ? What was Cabinet Secret of the Bourbons ? What boast could Fouché do, that a province governor / jesuit general / great Inquirer could not do ?
It makes them monarchies, not totalitarian state. There was no plan to mobilize all the population against itself and its neighbours.
More, free speech is only a part of the picture - one where UK was heading. Let speak about second class citizen and repressed national identity in "traditional" monarchies, for example. Is there no seeds for future dictators ?
Dictators did not need Napoleon to observe how to control a nation by censorship, racism, secret police, and overpowerfull armies. They had much more recent and complete examples, with the european empires which survived all the 19th century, and crashed in 1917-18.
