> When you're out of a call or your camera is off, we show users as "selfies" because we think those feel more human that just a green dot. Website viewers often interpret these selfies as being live video.

Even though in-app you encourage photos, maybe for the marketing website you could display this as avatars/cartoon-versions of the person (which presumably people can set, if they prefer)? It'd make clear that live video isn't mandated.
