Important context here is that many of these streaming services operated at a loss for years, and some still are. HBO Max didn’t turn a profit until 2023 and Disney only become profitable in 2024 after bundling with Hulu. AFAIK Paramount+ and Peacock are still in the red.
Point being, the introductory prices for these services were always unsustainable.
They are the ones who set the market so that’s on them. They are the ones who set what people were willing to tolerate. If it’s not sustainable, then it’s not a good business. They aren’t entitled to existing.
Armchair theories on paramount and peacock, so take with a mountain of salt:
Paramount will probably stay in the red because they are overly-catering to conservatives (a little too much emphasis on baby boomers as well), narrowing their potential audience.
Peacock just doesn’t have enough going for it period. Weak library and not a real first tier consideration for folks
Is that important context? I would say it's not. What if those companies already made massive profits and said "I think people are willing to pay more for this, so I'm going to raise the price." And there's absolutely nothing wrong with that. I've raised the price of my services many times in my career for exactly the same reason.
