I feel the same as OP but it's not due to lack of knowledge, it's good threat assessment. My political ideology is anchored entirely in the idea of empathy and being left alone so foreign actors trying to radicalize me isn't going to go far. Data about my political leanings are going to be an anomaly on the graph so it won't help anyone trying to sway a nation that already doesn't want any of my input regardless of who's in charge.

As for corpos, I would gladly buy all of my stuff internationally if it got me a better price, but now all it gets is slower shipping. Meanwhile, the local corpos actively spy on my every move so they can better rip me off. It's, a good idea to be worried about a gunfight happening down the block, but it shouldn't distract from the gunfight in your yard.

Yes, the best practice is to sure up against every threat, but in a practical sense, worrying about an international body harvesting my data is like watching a burglar open your front door and deciding you need bars on the attic vent.
