If you’re the one paying for internet access, you should also have the right to determine the content that you’re paying to have access to. While something like pi hole could be used to metaphorically take down most of the billboards without impacting the ground below it, even everyday users should be informed about the data advertisers are getting from them, whether it is anonymized or not. Hiding an important setting about data sharing near the bottom of a page in settings doesn’t help anyone but the advertisers.
I agree that it would probably be much better if the setting was set by a pop-up instead (as they say, most users would treat it like a cookie banner anyway), though I still think it’s as morally reprehensible as piracy. If you think one of these aren’t fine, you probably should think the other isn’t either. Like you paid for the TV but the TV doesn’t pay for the cable package; blocking ads removes their revenue.
I mean, correct me if I’m wrong, but don’t you also pay for cable. If I’m paying for a service I don’t want ads also served to me using it.
