Simple. The majority of the 'real world' don't want,
nor care, to engage in networking issues. The system
should Just Work. E2e solutions (or service enhancements)
usually propose changes to end-systems - your desktop and
mine - which violates the It Just Works principle.
Middleboxes make new service deployment an invisible,
and therefore rather tolerable, process for the average
user (for various definitions of 'user').

E2e solutions don't have to be fundamentally wrong for
there to be substantial resistance to deployment.
