Signal had 40 million active users in 2021 [1]. With 14 million in infra cost, that comes to .35 per user/year. Total expenses are about 33 million, so about .825 per user/year. All in all that seems very reasonable.

Definitely reasonable but the ultra privacy-conscious/paranoid can't easily donate or pay privately.
