You didn't have access to the entire market when Netflix was the only store. You had access to Netflix's market, and all of the other shows that are currently being funded by competitors didn't exist.
You could still use only Netflix today if you wanted to. The only difference is that now you are aware of what you are missing.
How many developers have consciously chosen to abandon the entire mobile market because of how toxic it is, because of how tailored the market is to a very specific sub-genre of mass-market apps and games? How many developers have abandoned iOS because their games touched on political or serious topics that Apple decided weren't suitable for their store? Many of us are not interested in creating the types of apps that thrive on the current mobile app stores, so we've abandoned the mobile market entirely.
When you can only see a tiny part of the world, you think that you have access to all of it. Once the walls get taken down and you realize how big the world is, then you realize how much of it you didn't have.
I completely sympathize with the frustration of not being able to get access to some of this stuff. I won't sign up for Netflix because of their DRM and anti-consumer practices. There are some shows I can't watch because of that. Trust me, I get the pain.
But having only one streaming platform forever would have been worse. So much of the original content that's coming out on Netflix only exists because Netflix had to compete. There are really good shows that are HBO/Hulu/Disney+ originals. I want that media to exist, even if I can't personally get at it right now.
