Comcast is already throttling and capping people using the internet. They lobbied HARD to kill net neutrality. I don't need to go to the theaters to watch a movie, even though that moment of Disney movie muscle flex lasted all of like a week, Comcast had been at this screwing the customers game for decades. I use my home internet to do all sorts of stuff, such as watch movies, YouTube, tv shows, and if eventually gets their way, they'll be charging a premium for the piping, a separate premium for the service, and then another premium on top of that for the product. All delivered at far less than their best effort (as the market competition *should it exist* dictates), and with terrible customer service to top it off.
Fox is getting sold off, and of the two available suitors trying to claim the prize, Disney is by far and hands down the better choice.
With Disney, Fox will have the option to run itself mostly independent as long as they produce quality products. They have some major in house competition between Marvel and Lucasfilm to live up to.
