Decreases what info Signal needs to collect and retain about a user. When using an SMS verification as a proof, Signal needs to log the phone number, because if they didn't, one spammer could use one phone number to create 10^99 accounts. When using payment as proof, they can verify that payment occurred, validate the account and then immediately forget about the transaction. One spammer would still have to pay 10^99 times to create that many accounts.

Payment leaves a huge identification trail because of all the know your customer stuff these days. If they accept monero or something then ok but I doubt they will.

  They could make it so all that is known by banks is that you purchased the service. Like how Nym does it or how you can buy Mullvad credits on Amazon. https://nym.com/zk-nyms https://nym.com/zk-nyms Ideally they accept Monero and do unlinkable payments but I doubt they will accept Monero. Hopefully they accept some crypto.

    > you can buy Mullvad credits on Amazon That is not the same thing. You buy a Mullvad scratch card on Amazon and you redeem the token string. Mullvad also offer the option to put your card number into the Mullvad website, and I'm sure many privacy conscious people would be very reluctant to do that. Card payments these days leave far too big a trail. The bank knows, the intermediary (e.g. Stripe) knows, and the merchant (e.g. Mullvad) has to keep records for accounting/tax requirements.

    It’d be pretty disappointing if they started including cryptocurrency features in their stack and didn’t accept it.

      They added that BS and then didn't do anything with it. Molly is going to add a Monero integration while also having various other advantages. They don't accept crypto donations directly or accept them for their backups so I assume they wont for registration.

  Also when they start dealing with payments there might be regulatory requirements like record keeping for a certain period.

It's still often cheaper (and faster) to grab a one-time verification number than to go through payment-based verification. Especially for anything that only needs a single SMS confirmation.
