They won't. It's the same data collection play as every other Google project
Just for clarity on this comment and a separate one, Niantic is a Google spin out company and appears to still be majority shareholder: https://en.wikipedia.org/wiki/Niantic,_Inc.#As_an_independen...
I kept wondering why a Google spinoff was named after a river and community in Connecticut, one of the least Googley locales in the country.
The connection is a ship, built in Connecticut, which brought gold rushers to San Francisco and was run aground and converted to a hotel there: https://en.m.wikipedia.org/wiki/Niantic_(whaling_vessel)
The company was named after the ship.
Google actually has released weights for some of their models, but judging by the fact that this model is potentially valuable, they likely will not allow Niantic for this
