For myself, Google never seemed to pick up which websites I visit. At least ads never followed me around. Probably because of my surfing habits: I open websites in a new browser instance and then close the instance. So no cookies stick around. Because I have set Firefox to delete cookies when closed. They could have tracked me via fingerprinting, but I have not noticed that happening.
Others surely have other browsing habbits. Keep cookies around forever, and Google knows most of the websites they visit. So when they google for a new fridge, they see fridge ads everywhere for a week.
But is that really a problem? What are the real world negative consequences?
Tech companies now seem to geo-fence their new products and keep European users out right from the start.
Which makes us even less productive by having less and less tools available.
Is it worth it?
Or are we just shooting ourselfes in the knee, having to crawl instead of walk, and turn into a 3rd world continent?
