So what? When I buy a magazine I may see whatever ads the publication publishes, and the companies can analyze the impact such ads have on their sales. There’s no need for said companies to know if I like to visit macrumors, disney, wikipedia, friends of the flat earth or cheapcarsforsale.com. I’m not paying to get spied on.
A magazine is made of paper with no connection to anything. It's a silo, and the business has a much less direct way of serving up relevant, successful advertisements. Think of of how many ads a mag has, it's half full of them. It takes much longer. Wouldn't you rather see more relevant ads if you are going to see ads at all? Ads aren't going away. How about a magazine that only has a few relevant ads? That sounds nice.
We are talking about the digital marketplace. The digital arena is rapid, smart, intelligent, evolving.
We just can't handle the relevant ads because we can't keep up. We see them as intrusive when really the marketplace is evolving faster than we are, "it knows more than me", and it's a bit unsettling, I agree. But I can also see the value in it. The smart businesses can win out even better than before.
Personally, I can see myself declining consent with this feature. But I can also see how that is potentially damaging to the market that has been built. The more relevant data the advertisers have, the better they can serve you as a consumer.
So yes, there is need for said companies to know if you like to visit macrumors and Disney, how much you make, etc. Because they can better serve your interests.
Afraid of big brother? Big brother is always watching, regardless of this feature. We cannot hide.
