You seem to lack a fundamental understanding of adtech and the mechanisms surrounding it. I'm not trying to be rude or dismissive, but it goes much deeper than "I bought a product and am being tracked." Everything digital collects information from you, with the primary purpose of selling the data to advertisers that target based on that data. It's not, "I bought a smartfridge, so I get what I deserve." It's "I went to mcdonald's, my friend used the mcdonald's app, now mcdonald's knows a ton of shit about me and I will be served ads based on it." I do not want Mcdonald's to know anything about me. That is the agency I am losing, because I cannot do much about it. You may think that's harmless, but there's been articles written about how McDonald's in particular has so much ability to surveil they basically can see like a state. Or stories like this: https://www.wired.com/story/mcdonalds-built-a-515-page-dossi...

There is no opting out without entirely opting out of every day life. Whatever viewpoint you're coming from always seems completely oblivious to this.
