Re: Maps, etc.
"Going back to Yahoo Maps: what incentive is there to develop a better product when there is a free replacement, paid for with the sale of personal details grabbed through the application stack?"
That may be true for Android--that there is no incentive to develop a better Maps product, but Apple and Microsoft have certainly tried to develop their own mapping systems (Apple's continues to blow goats, but that's another story) for use on their own platforms, which is really the heart of my point: even if Android itself has no effective combination in the field of licensable operating systems, there are certainly other successful smartphone platforms. Google is trying to control the Android stack, that much is undeniable, so the question is whether that control is ultimately harmful to such an extent that it is illegal, not just an annoyance to various and sundry fanbois, commentards, and Andrew Orlowski. I'm unconvinced that it is. Presumably, a world without Google would contain multiple competing ad brokers (which it does, and Facebook is trying to acquire some of Google's market share), licensable smartphone operating systems (I'm unconvinced that this is even a valid category to be concerned about), and assorted services (which exist already--there's nothing provided in the Google binary blob that can't be very easily replaced by something else).
There's a whole other discussion to be had that has relatively little to do with Google's supposed abuse of monopoly status, which is their data grabbing, and the answer is actually pretty simple: don't use Google. Buy an iPhone or Lumia instead of an Android. Don't use the Google suite of Web/cloud applications. Sell your ads through another network (although they're all fucking evil, anyway, so it's only a question of degree). Change may require some amount of personal effort, which I understand people don't like, but the options exist.
Tradition demands that someone come along and accuse me of shilling for Google. Let me assure you that I receive no compensation, direct or indirect, from Alphabet or any of its subsidiaries. I do happen to like Android better than iOS (I'm one of those crazy bastards who runs Cyanogenmod nightly builds), and my experience with the Google suite of applications has been superior, for the price, to anything else I've used. If it weren't, I would pack up my data and go elsewhere. And that really is an option--there's no Google service that I couldn't get from another provider, so where's the monopoly?
The final argument I anticipate is that, having left Google's services, I would leave them with all my data. Now, I do know a number of people who work there, one of them very senior, and I am assured that, in fact, when you press the button to delete all your stuff from Google, it's gone. It may, in some sense, still exist in the form of backups, but the live data set available to data analysis is toast, and recovery in the event that you say, "Oops, I didn't want to do that," is non-trivial. So I'm told, and I trust this person's veracity and knowledge about the inner technical workings of the account deletion process.
In short, if you take issue with Google's corporate behavior, you actually do have options. If you choose not to exercise those options, whose fault is that?
