I don't think it's unreasonable for users to expect an app that works, whether the app is "free" or not.
BTW I don't believe Intuit is running Mint as a hobby. If there is *no charge* for the app, then the users -- and our data -- are likely the product.
I believe if a business relies on APIs or screen scraping, then the risk of either link breaking should be expected. Intuit and USAA possibly need to know their customers better and establish a more robust relationship to minimize these perturbations. Or maybe they do know their customers and the population of users who care is too small. I dunno. I do know the hassle will make me avoid using USAA credit cards.
