The ones that will win are the ones that are supported by other businesses.
Amazon PrimeVideo can lose 100M viewers in a quarter, it doesn't matter, the money is still here, and it won't even make the stock price move by a tenth of a percent.
Netflix loses 10M subscribers in a quarter and its stock will be worth 0.
Netflix has literally no way to compete against the other giants. It's a one trick poney with a single revenue stream competing against companies that have virtually infinite money compared to it.
The ones that will remain are Amazon, Google and Apple. See you in 10 years.
