I can see number of linked devices of others in Molly(signal android fork). Why did signal allowed this in first place to show your number of linked devices to others? (programming.dev)

Because for linked devices to work it's like a group chat. Each app must encode their messages in the keys for all devices. So if you have two linked devices and Alice wants to send you a message A she has to encode it encode(bob1, A), encode(bob2,A)

So the clients MUST know about the number of linked device keys for the protocol to work.
