I'd like to add as an example the city in Europe I live in. The reason my city doesn't have public transit coverage in Google Maps is that they seem to have an exclusive deal with a local public-transit-route-finding company. I get it that business is business, free markets, etc. but this is clearly a suboptimal solution for an end-user. The website they give their data to is not bad, but Google Maps are clearly, objectively, better for both locals and tourists.
