Because comparing app loading time to website page load times is meaningless. A better comparison are common tasks in Photoshop, like selection, fill, layer operations, filters, etc. - things that are done constantly while using the application. I don't have any point of reference, but they feel pretty responsive to me. If the article was making a case that Adobe has been neglecting optimization for common operations, then bringing up Basecamp or other webapps would be relevant. I'm not sure how to explain it more clearly than that.
