To make the sensor square, the horizontal would be smaller, and thus the crop to get a 4:3 image would be smaller than from a full sized 4:3 sensor... plus you'd be paying for all that sensor you're not using if you regularly crop to 4:3... and throwing away even more if you crop to 3:2

On the other hand 4:3 is somewhere between 3:2 and 1:1, thus less of a crop for either... and if you normally shoot in 4:3 there is of course no cropping.

Oh, and the shutter would be shaped differently... can you say a taller shutter would be as easy to make or not more expensive?

The 4:3 ratio gives the most benefit to the most people, while a square sensor would compromise cost and/or utility for many to benefit a few.

Oh, and as someone else mentioned, the mirror.  Remember m43 has it's roots in 4/3 DSLRs  where a taller mirror might have required a longer flange distance, and thus a bulkier camera
