NFLX is publicly owned with only one share class and it only does video streaming so it does that.
Anyone motivated to do this for a smaller group would rather just run a private tracker. The overheads are enormous when you’re not negotiating in bulk.
Netflix has "optimized" their app to the point where you're cycling between the same 30-40 recommendations on every screen, just grouped a little different. The catalog shrinks every year. And they invest large amounts into producing their own algorithm-based content instead of acquiring more.
Netflix isn't owned by its subscribers is the critical difference. You don't buy shares of NFLX to gain access to the service, and subscribing does not come with any shares/voting rights.
