Disney is even more content limited and better for kids. Apple never got it right, cant see them fixing it now. And Amazon stuffed it between their mixed model where half the stuff you want to watch has extra fees + generally limited inclusive content, though the prime membership might buy that back. Both Disney and Amazon will fix the back catalogue with money I would guess, something Netflix should have done more aggressively before the competitors arrived.
While Netflix content is on the decline, there is a huge inertia in the best existing catalogue + 200million subscribers. It does surprise they haven't flooded extra content on the price increase as that is a good way to justify to users. Nothing worse than feeling there's a lack of content + pay increase.
My guess is Netflix keeps building the moat with content creation/ownership and we'll see mergers start kicking in as groups with back catalogues like HBO & NBC realise gaining/holding subscribers on smaller catalogues is hard and there more value in selling than renting. Who forks out more money at this point will probably win. Wild card is sport, that can be attractive and sticky if someone merges that in.
