You've misunderstood, the coding boot camp assigns homework, and sometimes that homework is: "Contribute to an open source project!" This usually takes the form of something like a pull request to "Fix typos in README" or something otherwise insignificant. GP is just saying that however you release your FOSS project, you're unlikely to get even that tiny level of outside contribution, so using "no one will contribute" as an argument against a mailing list isn't very persuasive. The argument that mailing lists suck, perhaps more so, but GP didn't opine on that.
