Netflix does listen to user feedback. Back in 08, the profiles feature almost got the ax before vocal user feedback convinced them to keep it. I'm sure they're listening, regardless of what the final outcome is.
I don't consider pissing off a large portion of your customer base causing a backlash so strong that you backtrack to be "listening to customer feedback". It's more like "poking the hornets nest & getting stung". Netflix has a history of shooting first & asking questions later.
As far as giving feedback or suggestions voluntarily as a customer, good luck. You can't do it on the website & any suggestion you give to a customer service rep stays with the customer service rep & goes no further. It's a sad state of affairs when the best 1-on-1 communication with customers Netflix has had as a company is their CEO doing damage control in Facebook comment threads.
I remember vocal user feedback telling them not to ax the "friends" feature too, but that's long gone. (And sorely missed, at least by me.)
I also remember vocal user feedback telling them not to switch to Silverlight, for that matter. I was one of the many who stopped being able to use their streaming service when that change went through, until I recently bought a PS3.
