> the company’s executives, project managers and engineers frankly discuss plans to design Facebook’s services so that users who leave for a rival pay as high a price as possible

Serious question: What are some of the rivals of FB these days ?

As for Apple, at least there are other, in many cases more powerful, mobile devices available, making the jump to Android from Apple isn't the big learning curve it once was. From a users perspective it's not that big of a deal usually.

From a developers point of view - there is a discussion Apple need to consider around how much they gatekeep developers. Anyone who's developed for the AppStore knows the pain. And to add on top of that extremely high fees, it's a wonder there are any 'indie' / smaller developers at all.
