ROF! Indeed, there does seem to be an abundance of 'hate and discontent' everywhere you turn these days ;-) However, as you've demonstrated to yourself, when you get past all the hyperbole and rhetoric and posturing there's often very little substance to the complaints.
Given the nature of the complaints, though, I'm not altogether sure they are really appropriate for the Better Business Bureau. I'm not into Clintonian linguistic contortions, so I just don't see any grounds for arbitration. As an oversimplification, it seems to me almost all of the students are misplacing anger on the university when the real sources of their failure and disaffection is entirely their own doing.
People tend to trivialize the inherent problems that are unique to distance learning, and overestimate their ability to meet the demands - self-discipline and self-motivation, for example.
The issues with adjunct faculty is much more complicated, but the business aspects are not unique to DL. Colleges have been relying on adjunct faculty increasing for decades. One dirty little secret, it by-passess entirely the minefield of tenure and sometimes cut-throat competitiion in/for tenure-track positions. Really, though it is essentially based on a fluctuating supply-demand, what is studiously ignored is that there is almost never any preparation of lectures or exams, and the primary function is not so much that of a teacher as it is a tutor - and, then, only on a contingency basis. [Note also that almost all the exams are proctored, and the 'grunt' work of grading and assessment is farmed out - which, in another cause for student dissatisfaction.]
College is tough. It's supposed to be tough. It really wouldn't be worthwhile if it wasn't.
As I've said before, college is not for everybody - never has been, never will be - but we put too much emphasis on 'college' when in fact what we should be advocating is the full spectrum of post-secondary education and training.
