only if you have a valid account with them. Which is the exact issue the original article was complaining about. Now, a Steam account stays valid even after the credit card has expired, but if you lose that account for whatever other reason, all your content is gone.
Which is worse than many ebook readers because they will allow you to continue to access your content even once the account is gone. Steam OTOH doesn't. No account? No login. No login? No content (their offline mode is too unreliable to be called that).
