That's a wholly different context. In that context, you're not selling usage data, you're selling conscious opinions/preferences. More than anything, all that does is confirm the assumptions Google is already making about your tastes based on your usage.
This is about valuing the usage data itself that's passively collected on the Android platform.
The real indicator of how outsized the value is compared to the perception of such is the revenue inflow.
There's no reason for the suppliers of raw materials here not to raise their prices (from zero). If anyone wants to provide it for less, so be it, but given that Google wants insight into everyone marketable, there's no reason for people not to raise their own prices for the data they supply.
Have you not seen their Opinion Rewards app for Android? They do precisely that.
