'Binge On' reduces the bandwidth requirements for videos by degrading video quality (and thereby the bandwidth required to stream video of that quality). That, in and of itself, isn't a problem. The problem is in the implementation.
If it *only* did so for 'Binge On' *partner* sites, the people complaining would have absolutely *zero* leg to stand on, because the reduced video quality is the trade-off for the bandwidth not being counted against your limits.
The problem, and what people are *actually* complaining about is this:
'Binge On' degrades the quality of *all* videos (streamed, or not) from *all* sites (partnered, or not), but still counts bandwidth from non-partnered sites against the users' bandwidth limits.
Both the users *and* the non-partner sites whose videos are effected by 'Binge On' have a justifiable reason to complain about this service as it currently works.
