I agree with everything you say, but think it should be emphasized that tech people at (for instance) Amazon are fundamentally in the same 'buy a mop' situation, except that Amazon believes that it is/can be so much more.

Fundamentally, it's clear that Target will never be a company that holds its tech people in awe - whereas at Amazon, you 'just' know that a single mop supplier is lower on the totem pole than a single DBA, for example.
