Unlike other messaging apps, they have access to encryption keys, when you change devices you only need to fill the phone number and all of your messages are available.
On other apps like Signal or matrix, you need to backup or export your keys to other devices, otherwise you can access previous messages.
It’s like you own an apartment and the doorman have keys to all apartments, if you lose the key the doorman can give you a copy, but also have access to your apartment when it pleases.
