Morally, I consider ads to be outright evil, especially the modern day cancer we call advertisement where they track every singular molecule of your existence. As soon as these scumbags stop hiring psychologists and other similar professionals to make the most addicting and psychologically impactful advertisements possible, then maybe I'll consider them less than pure evil.
I still have uBlock turned off on a few sites, though that list is becoming vanishingly smaller. 4Chan, funnily enough, has the best ads, where it's just old school banner ads on the top of the page and the very bottom of the page. No click hijacking, no embedded ads made to mimic organic content, no fucking audio and flashing lights ads. The only type of targeting those ads have is that the general audience that goes on 4Chan is into anime and Japan, both of which I don't care about. If the internet still had these kind of ads, I think adblockers would be much less of a "problem", but since 99% of them are invasive garbage, whoever is pushing them and whoever argues it's "immoral" to block them can go fuck themselves.
