Consolidations like this were bound to happen. In the mid 2010s we had a good thing, only one streaming platform with pretty much every movie and tv show. Then every studio got greedy and spawned their own platform, forcing netflix to produce their own shows. Now you have 20 tv networks all with their own subscription and all losing money.
This is the issue with content production being owned by the distributors too. It's too profitable to own the vertical because each piece of content is an effective monopoly, because to participate in culture requires watching it (piracy notwithstanding). Therefore, the "fix" is to regulate this monopoly - by making sure that monopoly cannot exist without cost. One "simple" way is, imho, to make content production and ownership of distribution strictly prohibited in the same entity, and to also enforce mechanical licensing of content (such that you cannot have content exclusives in the distribution platforms).
Movie theatres have similar restrictions with film studios in the past - to prevent this very monopoly. It's high time we brought it back.
