You can't scroll in them. You can't even intercept the tap event, you just add intents to views and iOS will open those intents.

The reason for this is supposedly battery life. For the bigger widgets on an iPhone that feels a little over the top, but the widgets system underpins the lock screen widgets which are now possibly always on, and the watchOS "complications"/widgets, which can also be always on. Because of that I can understand it.
