So every ISP in every country in the world is feeding thousands of terabits of data to a hostile American intelligence agency. Not just netflow, the actual contents, and not a single ISP employee has actually come out with this evidence.
I can believe IXPs in many countries will send netflow data to their state's intelligence org, but that's a long way from what was being suggested.
Another way to think about it, many websites the data gets transmitted before you hit submit, between various type ahead reactive frameworks, soft keyboards with networked spell checking, your AI powered mood ring, always listening smart watch/car/home etc. Grandad always said don't say anything on the radio you wouldn't say in public, well we're up to don't think out loud or see how your crazy idea looks in text before you edit the Mel Gibson tones out of it. Tinfoil hats are off, on, locked!
Ashburn, VA is the data center capital of the world.
When you type and hit submit, even on this site, your data will hit one of those data centers.
The few exceptions are government networks and China.
