One thing that you need to understand is that the usual business manager absolutely hates depending on technical expertise, and that the modern corporate world is fanatically anti-intellectual.

Vendor lock-in? compliance and security risks? stupid systems that cost the company an arm and a leg? nobody fucking cares.

Now, depending on an 130 IQ Engineer that basically holds the whole enterprise on his head? Anathema!!!!!!! Bus Factor!!!!

Also, the 130 IQ Engineer usually can't afford to wine and dine the business manager the way Amazon can. Or dangle the possibility of a cushy yet prestigious sounding job in front of them.
