I'm stunned that Apple collects $19 billion per year from Google to simply set Google search as the default on Apple devices.
The fact that Apple users don't know any better doesn't change this.
If they set a default, whoch is obviously the preference from a seamless experience perspective, how should Apple decide which engine to default to?
The obvious answer is let search providers bid.
If Google were paying Apple to keep other options off the platform, that would be a different story, but it's not a monopoly when a user continues to drive to the closest gas station despite there being an alternative right next door...
Google pays Apple to eliminate the need for choice. And Apple users are accustomed to choices being made for them.
