Bezos has liquidated so much AMZN stock he doesn't need AMZN's balance sheet for a piddly $250mm transaction. He might even figure out how to do something he hasn't done at AMZN and that's turn a profit. The last I checked, AMZN still had an infinite PE.
By keeping WaPo remote he can at least create the appearance that AMZN is corporately neutral for whatever news platform ideas AMZN pursues.

You mean like the $645MM profit they made in 2008, the $902MM profit they made in 2009, the $1.15BN profit in 2010, or $631MM profit in 2011?
Or is all that nullified by the $39MM loss in 2012 (due to LivingSocial)?
