> That ship has sailed and more revenue is to be made by harvesting user data
That does seem to call for supporting evidence. I write Apple apps, and they make it very difficult to access user data. I would need to know how they get it, and how they make money from it.
Put an iPhone on your Wi-Fi and log how often it calls out to some Apple web service. You might be shocked, or does it make it okay when Apple themselves are the ones it's impossible to have privacy from?
