That's not a bad thing. The general public has never wanted web companies to spy on them, and tech companies have been taking advantage of people's ignorance.

That's not a bad thing. The general public has never wanted web companies to spy on them, and tech companies have been taking advantage of people's ignorance. Everybody in the ad world knows it, too, and that's why so many companies are freaking out. They'll never get permission from people to spy on them like they have been. They whined about the "Do not track" header in the same way - they want to hide what they're doing as much as possible. If asking "customers" to opt-in in to your business model is going to hurt your business, it was a shitty business model in the first place.
