Or, indeed, what modern tech product has not been compromised by the NSA?

People are being a little naive. The US gets its "grubby" hands on every little thing you do, as does China. The question is not, "Which 'grubby' hands do I wish to allow to do my deep body cavity search?" But rather, "Why, exactly, do I need to submit to deep body cavity searches by 'grubby' hands at all?"

I think this claim about the NSA requires actual evidence.

on HN you get down voted for asking for evidence.

two clains were made:

* that the NSA as compromised all major tech

* the us gets it's grubby hands on all your data

in support of which no evidence was presented. a user kindly linked me to a Wikipedia page on PRISM. However, that program is only ISP data, requires a warrant for domestic purposes.

That's true, but different companies have different standards of manufacturing. Apple, for example, exert extreme control over their products, right down to the silicone. Short of a potato, they offer the highest degree of certainty and protection.

Meanwhile, Qualcomm has several programs running below the OS level that track users "anonymously" in various ways. Such systems can much more easily be co-opted by other parties such as governments.
