I already stated those words, you're not parsing closely enough.

Right after they say what you just said, they said and I quoted, "The Service may not be appropriate or available for use in some non-U.S. jurisdictions."

why would they say "may not" instead of "are not"? because they don't care if you use the services, they just want to be able to hide behind the other statement if you become a pain in the ass.

Notice that in his interactions with the company, they are not bringing to bear the statement that you think is so binding. They are actually saying that they want to help him.

If you live in a foreign country, and open a bank account and they tell you "it's for residents only", if you move out of the country they don't get to keep your money. Every modern country has ways of dealing with these issues, they've been happening since the days of sailing ships.

In modern times the new challenge is not long ocean voyages, but how to deal with a company that is online only and has no humans. But you know what the company has? Legal counsel, they have to. And you can contact that department/attorney and say you have a legal beef, and they will do something.
