> If you find yourself receiving too many unwanted spam calls or texts, you can easily turn it off for all phone numbers or select the specific ones you want to block.

So it sounds like if your aliased phone number has issues, you can block those specific ones. In theory, you can do that now from your phone, for individual numbers, but it isn't applied if you switch devices. So it's a very moderate improvement.

Additionally, your existing phone number is probably already overwhelmingly accessible to robo-callers, i.e. the cat is already out of the bag.
