Re: Targeted ads
"I have pondered recently about how bad the "i hate your adverts so I am never touching your company again with a bargepole" is, or isn't, for advertisers to persist in ramming their wares into your eyeballs at every opportunity."
We don't know, but more importantly, they don't know. I have a feeling though that that has almost no effect. I don't react like you do to advertisements*. I do my best to avoid them and ignore the rest, but I don't record the ones that get through that filter either to intentionally patronize their business or to punish them. In many cases, an advertisement that you're going to respond that way to is one of the many completely useless ones, ones for products you have no interest in anyway or ones where you have no choice**. Also, most of the people who are as averse to advertisements as you are would be blocking most of them, meaning that most advertisers don't feel the effects of your animosity anyway and wouldn't be able to categorize you into that group if they wanted to.
* The exception is when I get the same advertisement over and over again. The main place I notice this is on podcasts, which I listen to several of. In many ways, podcasts work the way I'd like advertising to: they're run by an individual, there's not much tracking of the downloader to try to target an ad at, and there are only a few attempts at centralized advertising networks for them. Unfortunately, that sometimes means that they don't get many advertisers so you just hear the same one over and over. Even then, I don't automatically develop a grudge against the advertiser. In a couple cases, I have built up a grudge against an advertisement or even a product, but I think those grudges are based on real defects with those rather than just having the advert repeated.
** Sometimes, a product is either the only option or clearly the best one, meaning that grudges against the company are kind of meaningless if you know you want to buy one. My ISP ran some annoying ads, but I need an ISP, this one has better prices and contract terms than the alternatives, so I ignore the ads which I'd be subject to regardless and buy their service anyway.
