I think, as noted in the article, that it seems Google sometimes uses names from advertisements as if they are canonical.
In my case, the city in question puts out a very specific, very legally defined map of each neighborhood, and has for more than a century. But real estate agents make up names for the neighborhoods, or fudge the boundaries to improve selling prices (thus commissions) and make their offerings more attractive.
About a year after a new neighborhood name is invented by a real estate agency, it starts showing up on Google maps. Then I have to deal with people complaining that our locations are mislabeled, because if it's on Google, it must be right.
It happens so often that I have an e-mail macro to respond to these people. And since the web site is very well respected by the locals, a couple of times a year I get requests from real estate agents, developers, and others, to change our maps to match their needs.
I got a particularly ridiculous one just this week saying that it's "our policy" (the real estate developer's) that maps should be drawn along a certain set of lines, and that we (the web site) are required to adhere to their policy.
I laughed.
