I paid Google directly; I am their customer. But they don't know what to do with user-customers, so they treat me like the kind of user-product that they're more familiar with.
Take with a grain of salt though. Pure speculations at best. Maybe they do just want device sales.
It's sort of like if Google sold a robot that happened to also steal money from your wallet. If they could get away with it, it'd be profitable for them, but there would still be something wrong with their behavior.
Mining your input and serving it to millions scales really well. As long as they can do enough to keep the majority of their users happy enough to continue using the product it is most likely more profitable to get the data than sell the devices given the market for android phones and the position they are in.
Google and their Pixel devices, not so much.
https://www.apple.com/privacy/ wasn't a URL until around 2010. Jobs died in 2011 and back then the page was just a Privacy Policy. Around 2014, they moved their privacy policy page and replaced it with a letter from Tim Cook which puts in writing that they don't monetize user data (if I remember correctly, this was in response to iCloud data breaches). In late 2017 they replaced it again with kind of a product page highlighting privacy.
Since Jobs has passed, they've move away from defaulting to a 4-digit code, encrypted phone backups in the cloud, moved from 2-step to 2-factor id, added a secure co-processor (with touch-id), made numerous moves to disable tracking cookies in their browser. From my observations about Apple, if they don't care about something it stagnates or goes away. All of those requires research, put more onus on the user, or cost Apple more per device.
Trust is a funny thing and I think it's much easier to lose than to gain. So they could move in another direction in the future, but so far it seems like they're continuing with a focus on user privacy.
