I'm legitimately curious what your solution is to sign up for Netflix if you can't use your ISP (Comcast, likely a monopoly with no alternatives).
I can't imagine calling up Netflix and attempting to sign up via telephone is feasible, nor is explaining to the average consumer the price is different because they're on wifi instead of data (and only their wifi, or select locations that use Comcast).
Someone said that Comcast charges more if you buy Netflix through them. Comcast does offer Netflix as an add on. You don’t have to buy Netflix as an add on through Comcast.
