I think there is something even worse than walled gardens and those are the closed platforms apple, Google and Amazon are creating. One thing is creating websites where they control the content users can see. But the web is still "open", even if facebook bans my content I can still create another website and share it with everybody (probably nobody will ever see it, but that's another problem). The real problem is the new tendency of app stores (Apple Store, Google play, Alexa skills...) If Google/Facebook/Amazon decide to block my content, I have no way to reach other users.
