Yes, this is fascinating. I can only imagine that as more and more developers flock to "free" SMS verification services provided by companies like Facebook (Account Kit) and Twitter (Digits), their long term outlook is even more unsure.

Could you share a link to the Firebase SMS verification you stated in your comment? Was actually looking for something like this... :D

Sure, no problem! Was just curious, it seemed too good to be true :D
