> I think that people can still have a shared reality as long as they understand that there is a disagreement. For example, Google could have done what many map makers do and explicitly indicate where borders are disputed.

But that's exactly what they do already, when allowed to.

Have a look at Jammu Kashmir. If you're not located in India or Pakistan, the disputed borders are shown as dotted lines rather than the normal solid lines for national borders. If you look at the details of any location in the region (e.g. the city of Jammu), it won't show any country.

Now, if you're in India, it'll not display any disputed borders and instead show the entire area being a part of India. But showing the dotted line isn't an option, showing these borders is required by the local laws. And you wouldn't want a multinational company to try to flout the laws of the countries they're operating in, would you?
