Google Maps Platform's Terms of Service are really quite onerous. You're not allowed to combine their data with any other data, so you're pretty much stuck with exercising just the features the API provides without any room for creativity. But you're also not allowed to create anything that competes with Google's own app offerings[0]. So it is very unclear just what exactly you're expected to do with these APIs. [0] Of course, not that they provide enough features through the APIs that you could. Things like StreetView photospheres are only available through a black box viewer widget or small, rectangular snapshots at configurable view angles. You can recreate the photosphere by combining several dozen of these shots, but each of them will have a very visible copyright watermark that you are contractually obligated to retain. You also don't get any access to their LIDAR depth data, so you can't do any sort of stereo reproduction. This all boils down to making the data source essentially useless for VR. Which would probably be considered as "competing with Google Earth" anyway.
