CNBC: In loudly criticizing the data-collecting practices of Silicon Valley Internet companies, Apple CEO Tim Cook is lashing out at some of his most valuable content providers. Half of the 10 most popular free apps on the iPhone are owned by Google or Facebook. Those services are free because they’re ad-supported. They help drive iPhone sales, and the iPhone accounts for more than half of Apple’s revenue. Cook didn’t name names, but when he said companies “have built their businesses by lulling their customers into complacency about their personal information,” he wasn’t leaving much to the imagination.
