>Password sharing is a symptom of cable companies inability (or indifference) to innovate on either content or price
Because video is barely profitable and HSD is very profitable, cable companies definitely do not like to sell TV as much as they like to sell HSD. Cord cutting is not as big a deal for the cable companies' profitability as most people think. If anything, the bandwidth required for streaming (now in HD but soon in 4k and then in VR) is so high DSL becomes less viable as a competitor and cable companies can raise prices for HSD even faster.
