I'm not clear on why people would be exposing MongoDB on a public address?

This habit of database-like software (does Redis still not offer authentication?) treating authentication/authorization as a second-class citizen is odd.

I guess it has proven to be webscale though [1].

Redis has offered simple authentication for some time: https://redis.io/commands/auth

Redis generally isn't put forth a first-class member of a popular stack and featured in getting started tutorials in the same way that MongoDB has been.
