Netflix was paying a large sum for Disney content, and passing that cost on to their customers. Without that cost, Netflix should drop their fees, but likely won't because they don't have to.
They won't begin removing content until 2020.
"U.S. Netflix members will have access to Disney films on the service through the end of 2019, including all new films that are shown theatrically through the end of 2018.'
I like what Disney is doing, they want control over the distribution of their own content. It's what they should've done to begin with (like HBO), they just needed to catch up technically.
Personally, my kids are getting older and don't care to watch Disney stuff on Netflix anyway, so why should I have to pay Netflix for that content (indirectly) if I don't watch it?
