But the alternative that the people who are against it are proposing is either to keep the status quo or kindly ask Google (and other ad companies) to stop existing, which is not gonna happen. They seem to ignore the fact that ad-tech is a huge industry and a large part of the internet relies on it. Basically the only way to make it go away would be to outlaw it.
(Also so nobody accuses me as being pro-ads: I hate ads and tracking, but sort of in a way like I hate being sick. I can reduce my exposure to ads and tracking (adblock, not using certain apps, etc.), but I know that complaining about it won't make it go away)
