We would simply not have many of the greatest web companies today if it was not because of ads. It's one solution that works and works really well. To call it immoral is to ignore everything that it has given us. You can complain about the annoyances of it and rightly so, but if you are going to bring in morality, first you must consider and imagine an internet or world without some of the most beloved businesses in it. I don't believe in a consequentialist argument either that just because something good comes out of an immoral thing then it justifies it given the benefits outweigh the harms. I would agree with you if that were true. I simply disagree with the assertion that ads are immoral or immoral to the extend that you seem to imply, I'd argue they're more of annoyance than anything else. And the burden of proof is really on you to tell us why ads are immoral since you're the one making the assertion, so far I haven't seen that, and until then or until when we find an alternative, ads are here to stay, and rightly so if I may say.
