What I've never understood is the argument that what Europe does regarding privacy could actually affect the privacy of other countries.
Sure, some websites detect your location and apply different rules to you but a lot end up just following GDPR and apply it universally because it is easier and cheaper to do that than do a "means testing" and apply specific rules. Creating all those rulesets makes for an increasingly complex system, makes it more prone to error (which includes doing those banned actions within California and resulting in a lawsuit), and just is overall more expensive. Determining country origin is presumably a lot easier than determining state origin too. Not to mention that California is the most populous state and the biggest tech sector. Pretty much the argument is ISPs have bigger fish to fry when they're restricted from doing something to a large portion of their customers.
No one and nothing are truly independent. That's always been a lie being sold. Choices you make affect others and choices collectively made affect you. It's literally the definition of a society. On HN we have these discussions about Chrome's dominance allowing them to have control over how the internet is structured. We've had these discussion about Apple's dominance influencing right to repair. And so on. Monolithic forces are never going to be stopped by single player boycotting. My usage of Firefox for over a decade never did anything to dethrone Chrome and I never expected it would, but hey, it also can't happen without people like me. Just needs to happen at a larger scale.
