I pay Netflix for convenience. I most certainly would not cancel my subscription if they removed DRM. In fact, I'd probably pay a bit more for the ability to download content for the rare occasions I want watch it on a different device.
Could you give an example (or many) since as you say the evidence is vast. I did a cursory search, and couldn't find sources, but perhaps I'm looking in the wrong places.
I can't find any musician, economist, or researcher who has ever complained about this, or suggested that DRM would help their financials.
