We estimate that by 2025, Signal will require approximately $50 million dollars a year to operate—and this is very lean compared to other popular messaging apps that don’t respect your privacy.

Funnily enough their biggest expense (sending SMS during registration) is making the accounts less private.
I imagine not paying for it and being overloaded with spam bots would be more expensive (otherwise they wouldn’t be doing it this way!)
There are lots of reasons to want fewer spam bots and verified identities other than cost.
