That may be true, but those 1000 streaming services are not all created equal... Most of them suck.
I'd also point out that a lot of those streaming services are the "long tail" of content that would NEVER show up on mainstream services in a meaningful way. Much like the rise of Amazon made it possible to find/buy books that you wouldn't really find in your typical Barnes & Noble because they were too obscured, these services get you access to obscure content that won't ever be a part of Netflix's standard catalog [and wouldn't ever be available on cable].
They complained when they couldn't get a la carte programming, and were forced into bundles. Now they're outside the bundle and it's harder to find the content they want, and paying for some of these services individually can be a hassle. They just want one easy solution, but they don't want that easy solution to be cable because they don't want to spend $100/mo.
So of course people are going to complain. They want all the content in the world, easy to find, and at ultra-low cost. They found out that unicorn doesn't exist, and they're not happy about it.
