Another irritating aspect to every one of these discussions is the argument that Google is an advertising company so therefore everything they do is and will always be about advertising. While Google has some golden handcuffs of advertising dropping a lot of cash in their coffers (which their competitors have as well, as an aside, to varying success. Microsoft has an ad branch. Apple has an ad branch), they have endlessly been demonstrating that they are trying to build secondary businesses.
The raw cynicism to discard an entire computing experience is not useful.
