If they were taking that approach, they would have absolutely first-class integration between AI tools and user data, complete with proper isolation for security and privacy and convenient ways for users to give agents access to the right things. And they would bide their time for the right models to show up at the right price with the right privacy guarantees. I see no evidence of this happening.
