Wonder what were the revenues from the monetization of collected data?

[_pmf_]

Do they actually collect anything that Google could not infer purely from location and time data?

I suspect that you never checked what information they collect. On Android, apart from location the app requires following permissions [0]:

  - SMS (read, send, receive)
  - Photos/media/files (read, modify, delete SD card contents)
  - WiFi connection information
  - Full network access
  - View network connections
  - Read Google service configuration
  - Modify system settings

Moreover, they have access to your payment information.
