Pokémon Go saves stranded group after Google Maps fails them

Interesting that OpenStreetMap knew anything Google didn't.

I probably wouldn't have even thought to try Pokemon Go, I would have just assumed that everything popular uses the same exact APIs.

Especially in things related to human mobility (biking and hiking) OpenStreetMap is much better in my opinion.

I suggest you give https://organicmaps.app/, which conveniently also works offline, without roaming (once you have downloaded the map data).
