If they take IBM/Oracle/etc. and things go wrong? you call them. they fly over an exec you can beat up and all is fine.

If you really truly can just punt, sit back, and even get to say "I told you so" when the system/software/service in question doesn't work, that's great. But... in almost all cases I've experience, it was still 'my problem', I just had far less control over making it work.
Suppose you rent your home and a plumbing problem leads to flooding and damage of some of your possessions. You take it up with the landlord and are credited two weeks' rent as compensation. Do you care about the specifics of the plumbing problem or the landlord's dealings with whatever plumber installed the system which later failed? Even if the plumber who turns up the house to fix the problem goes into detail about a previous plumber's ill-considered decision to apply PVC adhesive to ABS pipe, chances are that your interest is purely superficial.
And turning it around, if a plumber told me "hey, I'm not allowed to replace this outdated hazardous inefficient $pipeSystemX"... yeah, I'd want to get in to some details.
