Netflix is $15 billion dollars in the red, and every whole year for the last few have gone four billion further in the red.
Netflix sold their service at a loss for years, which is the genuinely untenable thing. You don't like Netflix's price rises, but subscriber numbers show the general public don't agree with you.
And yes, Disney are pricing their service at below cost currently in order to generate growth. But in the end that service will also need to be $30+ per month to stay in business. The current pricing is a loss leader.
I'm not sure that's quite accurate, according to NYT as of Q4 2020, "The company will still have $10 billion to $15 billion in debt, but it said it now made enough revenue to pay back those loans while maintaining its immense content budget."
Look I'm no expert, and I'm certainly not saying Netflix doesn't face a challenging competitive landscape.
The problem with $30 / month pricing is that, as you said, Netflix and the rest of the streaming industry have sold subscriptions at ~$10 for roughly a decade and this has set a expectations about how much those services/contents are worth. Thus when prices are raised (especially in roundabout ways such charing more for 4K or giving you "4" screens but cutting off "sharing") it begins to feel like a bait and switch.
It's true, most of us are willing to stomach $15 / month for what is, admittedly great original content (+ a large library of non Netflix produced content). But as more and more players jump into the industry, we're already seeing streaming fatigue, where what was once a promise of "cut the cord, pay $10 a month, watch what you want" is increasingly becoming subscribe to two, or three, or five different streaming services to watch what you want... with each service gradually raising the price... until you're paying $70 or even $100+ per month... at which point (price-wise) we're back where we were with cable (albeit admittedly with better content).
Also, these services also have to contend with the risk that, aside from just flat out piracy, if things get too expensive, people will just subscribe for a short period of time, watch what they want, cancel, and then rinse repeat. Sure they may get "$30 / month" but if they're only getting that 2 months out of the year... that's still a lot worse than $10~$15 / month for 12 months.
Just to be clear though, I'm not demanding Netflix keep prices where they are, I
