It's hard to look this up for me, so forgive me, but my assumption is Disney is not one of the big companies that can control the internet. I don't believe BAMtech has peering such as Netflix has caching servers like Youtube so I think this would be very interesting to watch closely.
My personal feeling is that if net neutrality is completely abandoned, Disney has more than enough money to print its way to making this work. I don't know if it'll be good or bad for them to be beholden to the same restrictions as other streaming services or if they'll magically become exempt. With all the properties in Disney's possession now I'm very much reminded of the phrase "too big to fail" but I'm very interested to see how this plays out. I'm hoping for a net positive for everyone involved but lessons of the past have me expecting the worst.
