It was a different time when the images/weather app was rejected by Apple. They were deliberately trying to prevent people creating thin wrappers around websites and calling it an app. And at the start it made a lot of sense.

Syncing over WiFi was a feature that users had demanded long before that app had been around and the name/logo are not distinctive. They are the most common sense choices you would use.

And widgets existed decades before Konfabulator thought to bring them to OSX. They were available as Desk Accessories in the previous versions of Mac OS as well as on Windows/Linux.
