Mark Zuckerberg has this to say about Tim Cook

Facebook boss Mark Zuckerberg is annoyed with comments made by Apple's CEO Tim Cook about customers being made into the product if online services are free, according to a profile by Time magazine.

In a lengthy piece on Zuckerberg, writer Lev Grossman says the only time the Facebook boss seemed irritated was when discussing Cook's comments, which were made in a statement last September.

"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," Cook wrote. "At Apple, we believe a great customer experience shouldn’t come at the expense of your privacy."

So what did Zuckerberg make of that?

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!
