We may not like the way these media companies operate under what, to us, seem like old-fashioned ideas that are out of step with today's world. Unfortunately, the copyright laws are just as old-fashioned and out of step. You don't like the current situation? Stop whining about the companies and instead get copyright law changed (good luck). That's the real problem.
So yes, it's stealing. Hey, the publishers don't even like the fact that libraries loan books for free! They certainly don't want you to share your books, although in paper form there's nothing they can do about it, and the laws have noted exceptions for everyday use of paper books that allow you to sell your book second-hand to someone else (they hate this, but the law carves out such exceptions).
Complain all you want, but it's irrelevant until the copyright laws change. The law says what you can and cannot do, and all the college debating in the world won't change that simple fact. You might not like how the law is worded, but you can't simply wave it away just because you get offended.
