The US are not sticking to their own laws. At least not if non US citizens are involved.
The US is generally obeying its long standing laws, its just that most people are very ignorant of what those laws are. A non US citizen outside of the US has zero privacy rights under US law, the NSA and friends are legally able to spy on such individuals to their hearts content essentially at whim. Entry into the US for non citizens is a privilege, and one that can be contingent upon providing full access to your electronic devices and data.
If a non citizen outside the US is using a US based service they don't gain any legal rights but the service itself has them. Whether or not the service chooses to exercise its rights and fight to protect its customers is up to them.
Did you hear about a guy called Edward Snowden?
Yes, what about the traitor? Very little of what he leaked actually violated US law and a lot of it was wholly legitimate NatSec operations.
Your answer sounds very naive to me. Industrial espionage is AFAIK not forbidden to US services. Thus consider the (current) US government as hostile and I am not alone. Maybe even some US residents will agree with me.
That depends entirely on what you mean by "industrial espionage". Its also not, as a practical matter, forbidden to any nations corporate entities. Incidentally, EU firms regularly engage in industrial espionage as well.
Bluntly, today, it is not the US that is going after digital privacy, end to end encryption, or electronic security in general. Its the EU and its member states pushing that.
