The issue is that people slide from it being a good map for some particular purpose to some blanket claim that all people really need to know is is <insert specific thing here>. The old classic case of this is geographically challenged reporters raphsodising about the London tube map https://tfl.gov.uk/maps/track/tube.

I love the London tube map, but when I lived there, it was all the more useful to me because I look at other maps so that I could know that certain stations were in easy walking distance from each other or some other place I was going to.
