I'm generally on the same page as you. I don't have an inherent problem with sponsored messages like some folks seem to have (ex. "outlaw advertising"). My primary issues are with the current ad network framework as it exists today. The bloat, the vulnerabilities, and to a lesser extent than most people are concerned, the privacy invasions. That is why I run adblockers. It's why I go through the effort of maintaining a pi-hole setup on my network.

I visit some sites than sell, manage, and host their own ad inventory. I make zero effort to block those ads and will even click on them if they're interesting. Most of the time they're images wrapped in an anchor tag, maybe the occasional SVG animated with CSS. I don't want personalized ads, I'd rather see contextually relevant ads if I have to see any at all.
