Oh, yes, because of course, cell providers whose phones run Android would never think of charging any kind of data tariff or making money in other ways.
No more or no less than on Apple's platform. In truth, with unlocked devices like the Nexus series cell providers have little to no say in the matter any ways.
That is, so long as net neutrality remains. If they start doing packet introspection and charging based on destination or traffic type, well, that is going to be bad for all mobile users.
