This whole article is just a bunch of fear mongering. From the article itself: "If you used someone else’s HBO Go password to watch last night’s season finale of “Game of Thrones,” you probably don’t need to worry about lawyers coming knocking. HBO hasn’t expressed any interest in preventing password sharing. For starters, they don’t have much of an ability to police it. Only 6.5 million of HBO’s 30 million subscribers have signed up for HBO Go, so it isn’t really damaging their business model." HBO has already stated that they don't care if you pirate Game of Thrones. Why should they care if you share your HBO Go password?

Actually the battery on a Toyota Prius comes with a 10 year/100,000 mile warranty, so even if you get one that only lasts about 5 years, they will replace it for free.
