These are $10/month subs which are akin to channel packages. Just because some will also sub to the Disney chan package doesn't mean they'll drop Netflix. Would surprise no one if the author were shorting Netflix.
It also doesnt mean nobody will drop Netflix. If you are paying money to Netflix and you are consistently not finding the content you expect to watch, you are going to question the value of your subscription. Some will cancel if they find the value too low.
