One of the worst articles I've read in recent memory, and another fine example of clickbaiting, heh. However, I expect no less from Apple Insider.
Spend 5 minutes with a Chromecast and you, like I did - will likely realize that Android may have been an option for the "OS" on it, it was by no means the best option. For what they are trying to accomplish with the thing, Chrome OS itself is far better. Chromecast is a neat little dongle, but not much more than a novelty at this point. I'd be willing to wager good money that most people were like myself and simply bought one because they were curious and it also came with 3 months of Netflix subscription, a $24 value. Making the actual device have a cost to user of $11. I'm not particularly impressed with the thing, but it's early days at the moment. It's got quite a few neat things about it and I'm eager to see what Google does with it in the future. Just a shame they made it Wifi only - would have loved to see it with a gig ethernet port on it.
As for capitalization and profits made off Android, if you think it was Google's goal to make money off a mobile open source OS directly you're crazy. Google is all about search, and if it takes making a mobile OS to lock you into their services and ad model, they will do it. It's working *extremely* well for them.
