Why? Why is lengths and areas more important than angles? You have to choose one, its essentially arbitrary. Personally I find it more useful to know what is parallel to what and what is at which angles from what, than some size. We have globes, so we know what the "real size" of Greenland looks like... this has always been a silly argument from the overzealous online looking for right wrongs that don't exist.

WEB MERCATOR DOES NOT PRESERVE ANGLES.
