it's not just the NSA
Let's say you make a home movie and make it available on the internet. No matter where you are in the world, or where the internet servers involved are located, the long arm of the law of the USA may reach out for you.
-if it includes any unauthorized music in the background or even just a TV on in the background it can be censored, people can have civil suits filed against them, and any internet services involved my also be in trouble.
-if it includes anything of a sexual nature, depending on the age of the participants and the various ages of consent in various jurisdictions, and depending on the specific acts involved and the various standards of decency in various jurisdictions, it can be censored, and people can be charged with crimes, and any internet services involved may also be in trouble.
-if it includes anything of a politically sensitive nature (say advocating for communism in the past, or advocating for islamism in the present, or even just environmentalism and/or anti capitalism), it can be censored, people can be "interviewed" by security forces and from there anything can happen to them, and any internet services involved may also be in trouble.
Internet services being in trouble can be anything from fines, having domain names taken, payment processing ended, physical servers taken, other assets frozen, right up to criminal charges against staff and management or even rendition or even assassination.
The USA can't go on about freedom of speech while any of the above is true. And if it is claimed that these are reasonable restrictions on freedom of speech (which I don't necessarily entirely disagree with), then why are white power websites advocating Nazi ideals considered fine when they are blatantly illegal in other countries. Once you go down the road of saying that some content should not be allowed, and the USA is quite a way down that road already (along with pretty much every country), then where do you draw the line, and just whose laws can be considered valid.
It is obviously not the case that the USA has Freedom(tm) and other countries don't. It is only a question of degree.
