The Snowden leaks made it clear that so long as the government has the means and motive to perform some kind of surveillance, they'll do exactly that. It may not be through the exact methods people are suggesting, but rest assured it is happening.
That’s another foundation of conspiracy theory: one specific example can serve as evidence for universal truth. Sure, the specific claims of theory A might collapse, but it might as well be true because it could be true because of past example B that is along the same lines.
I don’t doubt there is secret government surveillance we’d all be upset about. I’m not willing to use that general belief to assert the truth of specific unsupported claims.
The Snowden leaks weren't one specific example, they were dozens, involving every single big US tech company of any significance, and involving tons of different methods of surveillance.
