Yes? Why is that an unreasonable request? The docs make it sound like chats are permanently deleted. As of now, that's no longer true, and the way it's portrayed is misleading.
How is a user supposed to know, based on that page, that there's currently a legal requirement that means ALL deleted chats must be preserved? Why defend the currently ambiguous language?
It's like saying "we will delete your chats, unless the sun rises tomorrow". At that point, just say that the chats aren't deleted.
(The snark from your replies seems unnecessary as well.)
