Thing is, consider Google maps. It’s been harvesting data secretly and openly for a long time. I vaguely remember a time when Street View cars were found to be harvesting WiFi information in Australia and their response was, “oops, our engineers made a mistake.” Yeah, right.
But, Google maps is an amazing tool. All that traffic info? All those time estimates? Maybe it’s worth it. Maybe if people knew what they were providing, and the result they’d get, they’d still be happy to give all that “free” data to Google.
Putting aside the ethics of a company taking (stealing? or shall we call it, pirating?) all the ownership of that knowledge asset, if they make a really useful tool from it perhaps Pokémon players will be glad to have been part of such an epic achievement.
But for ordinary drivers, it’s great.
