What a giant strawman.
For starters, anyone "needing" to have every service at once isn't a thing unless you wanna pay for the pleasure. That certainly isn't any sort of comparison to cable, where you'd have to wait for something you want to watch to come on, if it ever did.
So we changed out the apples for some big fat oranges right there.
Second, I have many of these services and I don't pay full price for any of them. Deals abound.
I get hulu for $1/month and that's been a thing for years now. AMC+ was $24 for 12 months, total. I get peacock premium from Comcast for free for having internet with them. Paramount+ is $99/year with deals that can cut that in half. I have a year that was $50/year when I signed up last year. Disney+ was 3 years for $140 when it launched. I'm still halfway through that. HBO Max can be had for $99/year as well.
Netflix just doesn't have enough usable content that I care about. I certainly don't need any of it in real time, which you never had with cable in the first place. Put that $15/mo to use elsewhere and sub once in a while for a month to catch up.
Pro-tip: If you MUST have netflix, downgrade to the $9/mo basic plan. I don't see any picture quality difference that means anything, and Netflix is one of the few streamers that wants extra for 1080p and 4k.
If cable did indeed deliver every bit of possible content on demand at no additional cost, we might have a story here.
What we have is "I want way more than cable ever offered me, for less $".
If you want that, get youtube tv for $65/month and rejoice. Or wait for what you want to roll around to Sling at $35 and rising rapidly, while also offering only 720p picture quality just like netflixs basic plan. With lousy bitrate and resulting PQ.
