Sure, backdoors will slip under security audits, until one day they're revealed and you find out you've been pwnt all along.

I don't think the US is innocent either, of course tech that we use internally and export is probably backdoored out the wazoo.

I would rather assume almost everything I use is backdoored one way or another, and operate that assumption, rather than assume the opposite to be true and be wrong.

It's not a dramatic headline. Governments spying on each other and their citizens is the boring default state of the things.
