Bought it back down a bit in case the changes to the phone verification are related more to mana supply changes than anti-spam. I also read something on Notion in the last week or two that moving the login process via the Supabase migration will probably still use only Google, at least at first.

They recently added phone verification which seems like an enabler to not require a Google account. Buying some yes. It's a ridiculous requirement.
