As far as allowing you freedom to watch, Netflix is pretty good about things. You can register up to six devices to an account at one time, and stream simultaneously to two. It’s also pretty cool about passwords and log ons. No digging into your cable provider’s website to find your registration info, or worse, calling your friend with HBO and instructing them on how to find that info on their cable provider’s website.
And so Netflix knows that somewhere around 10 million of its subscribers are getting the service for free, by logging in under the accounts of friends or family, but rather than cracking down on those folks, they’re offering another option.
