Seems like there's a lot of blame on the delivery companies here, but reading the blog post, it reads like the developer simply doesn't have the resources to keep up with changes that Fedex et al keep making to their tracking APIs/interfaces. I assume the app mostly works by web scraping, which means putting in a lot of effort to fix things when Fedex decides to change the look of their website. I understand this takes effort, which is why I'm a happy purchaser and then paid subscriber of Deliveries, which I've been using since it was a Dashboard widget.
However, if they're not going to maintain the backend, what am I paying for exactly?
