Apple of course is one of the most famous walled gardens going, for instance FaceTime only works on the limited mobile devices they release. Why they can't make software for other platforms is beyond me. Netflix, Amazon Prime, Apple TV, and to an increasing extent, Disney+, are also walled gardens. [I'm sure you can list others] Oh sure, these are general access walled gardens which, for a mere $20/month, allow you to live the myth that it's totally open so you can wander around and cherry pick anything. If you're looking for general release movies or TV shows then it probably doesn't matter which one you plump for, they all have the same stuff at some point. BUT! With massive amounts of money these walled gardens are now creating movies and TV shows just for those inside the walled garden. This sucks, killing cinemas, destroying broadcast TV, making it a rich persons plaything, and removes the commons. $20 for Netflix $20 for Amazon $20 for Apple TV $40 for Sky
