Yup, it doesn't make any sense at all.
HBO should allow us to just cut them a check directly for whatever $ a month HBO costs on cable, to give us access to HBO Go. They could probably make millions more if they did this!
Right now, my cost increase to get HBO Go is around $60 + $9, or $70 a month. $60 for the cable subscription, $9 for HBO (or whatever it costs, this is an estimate)
There's no way in hell I'm going to pay that. However, I might be convinced to pay $9 a month just for HBO Go to watch stuff legitimately.
I don't know why HBO is being so thick-headed about this.
