Naive question: What makes you think that Netflix will probably die?
No matter how good I think netflix is, and despite their now long and good track record, they are entering a new fight bare handed against machine guns.
And Disney doesn't own all the content. Netflix need only be the streaming provider other content makers choose.
But they own about half (Disney Studios, Marvel, Lucasfilm, Pixar, 20th Century Fox, Searchlight, NatGeo, and I am sure I forgot a dozen others), and they might never licence it to a "competitor" again unless they are forced to do under some sort of FRAND unbundling of content and distribution.
I don't expect the GAFAM to play fair. They are going to arm wrest the industry to go through them.
