I'd like to clarify:
In addition to ending support for your ondemand programming on my TiVo you are also continuing to not support: HBOGO which is available to TiVo users on with other Cable Co's.
Is that acurate?
In addition I can suscribe to a number of premium channels like HBO Showtime Starz and many many more via the Amazon App right on my TiVo. See: Amazon Channels
So why wouldn't I just do that? Keep my TiVo, subscribe to the Premium channels I want to pay for and pickup everything else via Amazon, Netflix, Hulu etc.
Something to think about, I guess.
