Google as a default to other browsers doesn’t bother me. It’s the being the ad broker, the exchange, the browser, the os and the search engine that are problematic. They have demonstrated over two decades that they cannot protect the interests of either their users or the ad buyers. Disabling cookies is essentially meaningless when you’re forced to sign into your browser or os. Absolutely no ad exchange can act in the interest of their users’ privacy when they have a browser or os that mandates you to sign in. And yes, even ad buyers get screwed by Google’s exchange (Google’s real customers). There are many fraudulent publishers that stack ads but get paid out for false impressions, Google still collects on fake impressions and has little interest in decreasing the fraud since they have a 30% take on the impressions.
The ideal outcome is that chrome is spun off, android is spun off, and the ad exchange is spun off. Google can keep its suite of productivity tools and search engine and run ad words. That’s a completely reasonable and still extremely valuable business that is highly defensible. I think their interests can align with their users and customers in that scenario. As it is right now, I don’t think you can have the business model they have and not have serious conflicts of interest with users and advertisers.
