The problem is that a chosen few got help to put their apps on there and be first-to-market, while everyone else was left in the dark with no documentation and not even an expectation of when the SDK would be released. Up until today it supported a tiny subset of what it claimed - MPEG-DASH playback had to be done via dash.js, which can't even run smoothly on the device, SmoothStreaming playback was completely impossible unless you rolled a complete HTML5 player from scratch using MSE. Meanwhile, the Netflix app isn't even a proper HTML5 app - it's literally flashed onto every device sold and opened via a command. The Hulu app's player is named "chromekey_player.js" so presumably they were able to start before the Chromecast was even called the Chromecast. While Google are under no obligation to provide an even playing field, it wasn't a great start for the platform - hopefully things will be better now.
