> their justification for dropping SMS capability from their Android app ... was a little more transparent about the obvious cost aspect

I'm not following. Signal gets stung for the registration SMS costs because they send the SMS to the user. They don't pay when one user sends an SMS to another user. If you send an SMS, you're the one who pays.

(I didn't realise they were moving away from phone numbers. Don't they they stay mandatory when PNP comes along?)
