That's a goalpost on wheels. Anyway, it doesn't change the fact that the GP offered than even under the same regulations, public facilities perform significantly worse than private ones.
When privatization works it is good but it doesn't always work. The current cable industry seems to be just exploiting a monopoly so I think "privatization" has already failed here
I only have 1 possible cable provider and it's pretty expensive and their service is terrible. It's gotten better in they last 10 years but that doesn't mean that it is a competitive market.
EDIT: Maybe it's changed but when I checked last they had low customer satisfaction but really high profits, which is bad for consumers and (I'm not an expert here so take with a grain of salt) would be really unlikely if the market was competitive at all
