Why would I believe a company that is bound by law to (a) hand over my data and (b) tell me they're not doing that.

I can't be convinced it isn't happening at this point because we have evidence that it is from the government.

They aren't bound to tell you they are not doing that. Again, i'm not sure where people get this idea. They may be compelled to be silent about it, but not compelled to lie.

Evidence, probably. People say stuff all the time and it's mostly marketing and drivel.

Evidence to prove a negative?
