I'm not sure what you're comparing. Netflix's Jessica Jones, Daredevil, and Luke Cage were standouts. WandaVision and Loki are certainly flashier, but are they really better shows?
4 out for the top 5 grossing movies of all time for Disney (adjusted for inflation) are Marvel IP. By comparison none of the Marvel shows on Netflix have been a commercial hit for Netflix. Looking at the list of most watched Netflix shows none of those make the cut.
Basically Disney is well suited to turn Marvel IP into dollars and Netflix just wasn’t.
Oh. Well, I can't argue with that, especially since Netflix almost certainly never had the necessary rights to develop a revenue stream from merchandising. There is probably no other company on Earth better suited to turning IP into dollars than Disney, especially since they've acquired Pixar, Lucasfilm, Jim Henson, Marvel, etc. Netflix has only started trying to make tentpole 'blockbuster' (irony intended) movies in the past few years.
Probably not and that is why they didn’t bid, and the Netflix execs are in a better position to know than us… but I think the comparison is a little tilted against Netflix at least.
I imagine they had to pay for the IP for The Witcher and Altered Carbon.
