The USA is unique for a great many things and while the freedom of speech is not one of them, it is something that is not shared across all borders. And like all laws, it is your responsibility to know what the rules, laws, and regulations that any country bestows upon its populace.

Many places don't have the first amendment. The limitations imposed by the governments may be about certain individuals, events, or even the government. Sometimes, these limitations are enforced by surveillance within your room or other places. 

Speaking of privacy, that is not a true expectation that you would experience privacy. Some countries monitor everything. 

Remember, you probably live in a free country with privileges that extend beyond those of others.
