Looks like teenagers are going to have fun playing Pokemon Go, and now have faster food deliveries.

It's useful to map the world, this is what Google / Baidu / Yandex Maps are doing too.

It is indeed useful.

The question is how one stands on the monopolistic collection by a commercial entity.

I personally don't mind to share GPS traces and other data with i.e. open streetmap, as I directly benefit from the data as well and it's more or less equal between different entities.

I try not to give too much to Google and similar companies as this increases their competitive advantage, while my benefit is small.
