There's a corollary to the fallacy of appeal to authority, which is that it's also a fallacy of rejecting an idea outright on the grounds it doesn't come from an authority. It's an insightful observation whether or not you like Bezos.
I don't really have an opinion about the man outside of "growing a business", but how on earth does this benefit him? I don't know where on earth you got "authority" from as i didn't invoke this concept at all.
