Last September, Apple chief executive Tim Cook write an open letter about privacy, that had a thinly veiled insult directed at social networks.
A few years ago, users of Internet services began to realize that when an online service is free, you’re not the customer. You’re the product. . . . Our business model is very straightforward: We sell great products. We don’t build a profile based on your email content or web browsing habits to sell to advertisers.
It turns out that Cook's missive greatly annoyed Facebook chief and founder Mark Zuckerberg, so much so he ignored his handler to tell a reporte at Time, "A frustration I have is that a lot of people increasingly seem to equate an advertising business model with somehow being out of alignment with your customers. I think it’s the most ridiculous concept. What, you think because you’re paying Apple that you’re somehow in alignment with them? If you were in alignment with them, then they’d make their products a lot cheaper!”
