Were you tricked, or were you just poorly compensated for your time?
Frankly, with the amount of real-world walking required to progress in Ingress and Pokémon Go, most players were compensated by the motivation to get a decent amount of exercise, which had a net positive impact on their health. Most exercise apps require users to pay subscriptions for the pleasure of using them.
Frankly given the numbers of hours of entertainment most people got out of Pokémon Go, I suspect this might be one of the cases where people have been best compensated for their data collection.
