What I find interesting here is that Roku is using business practices similar to Apple and nobody seems to have a problem with it. If I told you that an app store was limiting the types of apps you could add to your device while also controlling the update process, lots of HN readers would call that out. As far as I'm aware, Roku also has a way of capturing subscription revenue as well.
By alk means call out Google for their garbage business practices. But don't let Roku off the hook either.
