This is a great map, they should show it alongside the typical one when teaching geography. I'll show this to my kids later, see what they think and ask them to find some countries on it.
A similar change of perspective "trick" is knowing that when we look up at the stars, it's not really "up", it can be "down", too. Imagine being suspended head down, feet stuck to the ground looking at the space below, with billions of light years worth of almost nothing out there. A bit terrifying, I suppose, so maybe don't think too much about it :-)
"The enemy's gate is down"!
They also take an absurd cut of developer income and saddle devs with costs that they don't always want. (Selling on Steam? Valve takes 30% and forces you to moderate the forums on your listing page that you cannot opt out of.)
They also have an internal culture that's been fairly regularly criticized as being pretty uncomfortable for women and minorities.
Valve has done some cool stuff, but let's not lionize them too much. They are probably better than an average company, for sure, but it's important to remember that they are also sketchy in some very gross ways as well.
