It reminds me of when I was in 8th grade and I discovered Visual Studio and made tons of "apps" that were glorified iframes with a menu and an about box for no reason other than I could. It's a clear case of a solution in search of a problem syndrome (not that there aren't proper use cases for complex web/desktop apps, obviously).
Same goes with a lot of sites that seem to be built as web apps despite not needing to be apps in any shape or form.
