Fair enough - Google sells advertising against data which they search and index, which is publicly available.
As opposed to Apple and Facebook, where you have to join a system that holds your personal data under their lock and key, before getting to access data that they will sell advertising against.
And everything in their ecosystem is not publicly available.
EDIT: Reducing the data to "goog just wants to sell against FB and APP data", is to reduce many major issues into irrelevancies, which is incorrect. Its not about 'just selling ads'.
For Google it is very much about selling ads. That's their business.
The data is obviously worth a lot of money to Google, and yet they want it to be given to them for free.
That seems like an unrealistic expectation now that the market understands how valuable data is.
