Like it or not advertising shapes the world we are in. Where do you think the million dollar super-star athlete salaries come from? Advertising. Free programming? Advertising. I can go on. It's incredibly unlikely you don't own at least one thing you either got for free due to advertising or was subsidized by advertising.
No one likes advertising, but everyone wants free stuff. Why do you think advertising is attached to free stuff? Who do you think is paying for the free stuff?
Companies that pay advertisers want a return on their money spent. That's what all the tracking is about - to justify the money spent. I can understand them wanting to get that data, but I also understand not wanting to be tracked and targeted. Even if by an impersonal computer, it's creepy.
Full disclosure here - I work for an advertiser. And here's hilarity for you - nearly every computer in this department runs ad-block to stop viruses or who knows what else from getting into the system. There's a lot of abuse out there by the unscrupulous to the downright criminal "one simple trick scam" idiots.
There's a lot of problems with the current system. If you can devise a better system for all parties there's a lot of money in it for you, go for it.
But it's two-year-old level childish thinking at it's finest to think you can get all the free and subsidized stuff out here in the world without the advertising that pays for it. Sure, you can block it - but if the blocking ever rises to statistically significant levels then the revenue model will be forced to change, and probably not for the better.
