People say this often, but I have never seen it manifested in a viewership chart. Just using Nielsen data as an example, Netflix absolutely dominates the Top 10 chart, with 7/10 of the programs:

Anecdotally, when traveling outside the US, Netflix & Disney are really the only providers I have seen have any kind of footprint.
Is there any data to back up the "content quality" complaint, or is it just a personal preference?
It seems to me that Netflix still has the most generally appealing content. Yeah Disney has some of the biggest names, but unless you 1. have young kids or 2. are a huge, not burnt-out Star Wars or Marvel fan, Disney+ is a pretty poor service. Most of the other services fall somewhere else in the middle of that spectrum.
I feel the opposite. Marvel's content are getting really tiring now. Superheroes with superior technologies choosing primitive societal and political structures really turned me off. Not enough great action flicks, or binge-worthy dramas like Oz and Strange Things. Not enough international hit shows. Not enough old catalogs.
I'm no fan of Disney, but you have to give it to Bob Iger. He just paid out the nose to buy every piece of valuable IP: Pixar, Lucasfilm, Marvel, Fox, even Jim Henson.
The amount of content they now own is insane. Everything from Sunny in Philadelphia to the Muppet show to Alien to Avatar to The Simpsons to Starwars. It's nuts... you can't throw a dead cat in Hollywood without hitting Disney IP.
Meanwhile Netflix makes something worth streaming every year or two, if that.
