>[Netflix has] "slowly reconstructed the old vertically integrated studio system. The company is an integrated production and streaming service."
Netflix is probably the least integrated business in Hollywood when it comes to production. To use an analogy, think of content as sausage.
Netflix doesn't make the sausage and they don't care about how it's made. They pay people a lot of money to do it, and that's about it. They're in the business of distributing the sausage. They also buy a lot of bulk sausage that they found at a sausage festival, meaning they had no stake before it was made.
(some) Traditional studios do care a lot about the making of the sausage. To make sausage for them, you have to buy their spices, use their casings, and go to a meat supplier that they recommend and might have a co-ownership stake in with other sausage distributors. That's not a bad thing, making sausage is complicated with a lot of people involved - the studios give you a good deal by removing that complexity, and helps keep your costs down before you get to see a profit.
