Bandwidth management is a tricky topic, very nuanced, and varies from provider to provider. In someways, despite some of the net neutrality discussions focusing around disclosure, this may end up becoming a bit of a "secret sauce" because it is so heavily tied into quality perception. In the end, everyone has to throttle--pre-emptively or not at least some of the time; who/how/when makes all the difference.
If I read between the lines of a lot of what's going on in the industry, I see that most of the bandwidth management is focused around getting the best performance for the best 90%-95%. The fact that cable msos will aggressively throttle some customers in some situations in the end doesn't matter--they can leverage the expanded capacity to give a very good experience to the bulk of their subscribers that can be hard to recreate using much lower capacity connections. And, in the end, it's not like you actually want the 5-10% as customers anyway, since they are typically unprofitable... By and large, their bandwidth management has better: most of the major providers do provide a pretty good experience if you're not in the edge of their model. The small companies will typically be a lot less refined in this process, so it will likely impact a lot higher percentage of their customers.
