And if the sole developer of Elm forgot to pay for their domain that hosts packages for Elm all those projects would be broken forever.
When your parent said "one-man project", he is referring to Elm, not the project using Elm.
Elm was/is highly dependent on one person.

Hundreds? I think that's overshooting it.
I know multiple companies that use Elm and many people depend on them for their livelihood.
I would not recommend it due because it has never been a really open source project and only the core maintainers were allowed to write libraries that interfaced with JS apis without the need of ports.
Still, it baffles me how many people would chime in and feel compelled to comment regardless of the fact that hundreds of projects out there make money with Elm.
