I'm familiar with Whatsapp and its relationship with erlang (there's RabbitMQ as well, which I always forget when asked..)

But they're the only real case studies

If I were to say "Go", people can point to big projects like Docker, Kubernetes, etcd, Googles internal use, and a few others (Uber?)

Erlang just doesn't have that sort of buy in, which is concerning because it's been around longer than Go (as a FOSS language), heck it's been around longer than Python (but it was proprietary back then)

Speaking as someone that's never used it, that's got "don't bother unless you've got an academic interest in it" written all over it
