It's almost beside the point. Enterprises want to pay someone for support (and, more importantly, someone to blame when things go wrong) rather than (rightfully) attempt to put something together with duct tape and bailing wire.
The point was that 'enterprise' is not any less 'duct tape and bailing wire'.
Unless you get value out of shifting blame to a vendor or some contract thing, there really isn't much use throwing money at it. In some sectors that's probably still a requirement. I hope I never get to the point where I have to go back to that.
