In fairness to Netflix, in the old days they only had to own a copy of the DVD in order to rent it out.

Now they have to secure rights for every title they want to stream. That’s a lot of work (and cost) for a hundred thousand titles, especially when your competitors own some of the studios that license those titles.

Disney, for example, owns the Disney / Marvel / Fox / Searchlight / Lucasfilm back catalogues and wants to hoard much of it for its own streaming service.
