Agreed. I prefer setting it up myself and have had Signal backing up to my home server for a few years now, but for most users an opt-in with a basic free tier and cheap enough paid plan makes a lot of sense. Glad to see they're finding potential revenue streams that don't compromise their focus on privacy and security.
