You are not obliged, you are forced under threat of violence to gather information about your customers so that governments around the world can control what your customer's money is being used for.
Being obliged == being forced to, AFAICT.
You can't imagine the angry thoughts that go through my mind when I read bs propaganda like this, I'm pretty sure if they already tried to attack people for thought crime I'd get the capital punishment. 
Chill down man, you'll only get an ulcer for nothing.
I usually get angry with authoritarianisms I see happening day by day, but you're letting yourself go too easily if just this OP was enough to get you angry. It won't do you any good.
Plus, the correct wording may make a lot of difference in the results, even if in the end it's the same thing you're saying. It's probably wiser for OP to use the words he used instead the words you'd used. That will probably make his job and the business of his employer last longer. Plus, he didn't need to lie.
Btw, remember they are using their own identity here. When my parents were teenagers, publicly speaking about the state the way you've just done here would probably get them in jail, or worse, make them "disappear". And even recently, a political blogger in Brazil just got shot 6 times, miraculously survived, and now is facing a lawsuit from a federal representative bitch for "moral damages", while the investigation about his attempt of murder is practically archived already.
TL;DR: Don't look for troubles. Take care.
