As an aside, I have often wondered at the way North=up became, and remains, completely universal. An upside-down globe "looks" as wrong to me as an upside-down portrait. Obviously there's no reason this must be so; it's nothing more than familiarity with the shapes of the continents from a particular perspective.

Some day, I'd like to have a globe or a big mercator-type map with South at the top (i.e. with the written labels upside-down from normal), and see how long it would take to become accustomed to it.

THAT kind of inaccuracy bears almost no resemblance to gripes which emerge about the tradeoffs in 2d map projections regarding inevitable (as opposed to highly arbitrary, political) shape and area distortions.

Maps which have south at the top ARE sold and do just fine in the Southern Hemisphere.

The point actually remains that the market has not rewarded any maps which have the kind of distortions which would be required to specifically and artificially inflate the size of Taiwan relative to China, without much affecting anything else.
