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."

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.
