Not great for a chat app, which needs ongoing active servers and someone to fix stuff that breaks, even if you feature-freeze it.

  Pretty great for a chat app used by a few billion people, a few $billion is enough to keep things running for many decades. e.g. banks do exactly this, with much more critical and complicated infra.
