I cant find any information that discusses the security risk. But it would seem that this transfering all content to the owner of the phone number is a standard feature.
So, maybe its not discussed because it doesn’t frequently happen.
It doesnt seem like a trustworthy way to ensure users content remains secure.
If someone trys to register with an existing number then it wont work if its already being used.
Got a source for that? There have already been multiple contradicting sources posted saying this isn’t true.
