You're paying negative $5 for cable, but how many other people are doing that. I don't know the going rate for Comcast cable, so I'll use the $25 basic service fee from Eastlink in Canada (my service) as the exemplar.
Assume there are only two possible monthly payments for Comcast. You can get the basic service for $25 or you can get the "they quit the service but we're keeping them on the books" service for $-5. Given these prices, you would need to have 3.4 subscribers at the latter price for every one subscriber at the former price before Comcast and Netflix would be making equal money off subscriptions alone. I seriously doubt 77% of Comcast subscribers are ghosts like you, so I stand by my argument that Netflix is massively financially outgunned by Comcast.
I don't disagree but time is not on Comcast's side. Anyone who went to college in the 90s and younger is a huge threat to cable tv.
Not entirely true. I'm part of a growing number of people that have cable tv who don't actually use cable tv. Let me explain. Once I explained to Comcast that my household no longer watches cable tv and that I'd rather spend the money I used to spend on cable tv for faster internet (up to 50 mbs). They in turn explained to me that if I have super basic cable plan for $9.99 / month, they would give me a $15 discount off my entire monthly bill. So for a $5 monthly discount, Comcast gets to keep me as a ghost cable tv subscriber.
