But need is need despite advertising... it sounds like you are suggesting a case where there are no alternatives. If I don't necessarily already have a preference, I frequently choose products that compete with the annoying advertiser. Maybe they get the message, maybe they don't, but I know I'm not supporting that kind of behavior.
Also, it is important to distinguish, I don't mind catchy or memorable ads. I do mind annoying and intrusive ads. I don't go out of my way to run ad blockers or anything like that, but my local news website recently pushed me over the limit, and I took measures to ensure I maintained my quality experience on their website.
