Hiding shady or unexpected stuff in the TOS is illegal in the EU and other countries for example. So just because some companies behave amoral, that doesn’t mean we just have to accept hundreds of pages of legalese being able to dictate us.
Niantic have never made a secret of the fact that they're crowdsourcing to enrich their mapping data (eg data from Wayfarer and Ingress was used to seed Pokemon Go and Wizards Unite). I can't see it as a sudden gotcha, as it's practically their USP.
We don't have to accept it no, but also you shouldn't be dumbfounded when it happens. Always assume everyone is doing it.
I don’t think there is something amoral here. Niantic explicitly sends players to take videos of places for rewards. It’s not like it’s done in a sneaky way.
Being somehow surprised they actually plan to do things with the data they have you gather is a bit weird.
