Except for, you know, allowing those websites to exist in the first place? Ads and data are nothing but a form of payment, the gold or salt of the internet age.
The alternative to ads isn't no ads, it's paywalls and subscriptions. If ads didn't exist or weren't as accurate as they can be with invasive tracking, we'd have far less content out there, and most of the existing content would be locked behind paywalls, making search engines even more useless than they already are. There would be no free video hosting on Youtube, no free music on Spotify, no free educational resources for those who can't afford books, and calling your friends on another continent would still be a few dollars per minute. The internet would be a much sadder place even if you were rich, and almost completely inaccessible to you if you were poor (or a teenager without a bank account / a resident of a sanctioned country / an undocumented and unbanked immigrant.)
Ad Blocking is a "tragedy of the commons" problem, your internet experience is better if you do it than if you don't, but if 100% of users were to start successfully blocking ads everywhere, the experience for those same users would quickly degrade.
