They don't "just have taps" in whatever isp you come across. And they certainly, and i cannot be clear enough on this, they don't just spy on Americans. It's literally the one thing they expressly forbidden from doing
I’m not sure there was ever a time when they didn’t have taps, but this is definitely not true.

You can’t build centralized systems that enable spying and not expect people to do the “forbidden” thing. We have to build systems that make this impractical.
