This comes from the dated perspective that free trade is universally good. Nations create their own trade rules and they ought to be able to enforce them. I consider that far preferable than attempts to exert extraterritorial control over services from other countries.

If, say, Uruguay doesn't like content on Facebook, they are free to block it. In their opinion, they are protecting their citizens and that's ok. It should not produce legal action that could result in least common denominator style global content censorship.

In an ideal world, there would be no country level blocking but invariably laws will differ.
