They may make money off ads but I don't think they have any real incentive to lie about what they're doing. Because most of their users don't actually care. I would be curious if anyone knows of any scenario where Google has outright lied about what they do and don't do with information, because I've never heard of it.

For me, I moved off gmail for other reasons: my email is too important to randomly lose access to because e.g. their youtube AI thinks I'm spamming a channel on Youtube. I look at all my data in Google as if I might lose access to it forever some day, because someday I might, with zero recourse.

I tore off my nest thermostats and replaced them with dumb ones. I miss the ability to change my heat remotely, but at the end of the day. I don’t need that functionality.

They say they won’t use it to sell ads:

> “To help you easily view and keep track of your purchases, bookings and subscriptions in one place, we’ve created a private destination that can only be seen by you,” a Google spokesperson told CNBC. “You can delete this information at any time. We don’t use any information from your Gmail messages to serve you ads, and that includes the email receipts and confirmations shown on the Purchase page.”

What guarantee is there that this is not being used for other purposes? To train other kinds of models? To, say, monitor other people’s AWS bills, in order to optimize their own offerings? How likely is it that such a project was approved with no gain except adding perceived value to the Gmail product? I have a hard time believing they would do it only for that.
