Imagine if Android’s Gmail app made you click the trash to save something. We would certainly see complaining blog posts and snarky tweets all over the place. So why does Instapaper get a free pass?

As we can all plainly see, it doesn't.

Imagine if you could "safely remove" a disk from Apple's own file management app by dragging it to the trash.

Instapaper's UI is discoverable and forgiving, which seems far more important than its particular choice of "iconography" when actually interacting with it.

Actually, when dragging a disk to the trash in OSX the trash can turns into an eject button.
