Not only is it a large user base, but a varied one too. Flask, Django, FastAPI, Twisted...and that is just to name the web frameworks! We have scientific use, research use, cli tools. Perhaps in some cases end users (developers or not) of those tools may not be aware Python is the foundation of said tool.
Anecdotally the Erlang users I've met have been incredibly knowledgeable and in tune with the language features and development. I find that pretty cool.
In my opinion, an argument can be made that Elixir is the most prominent web framework for the language, so developers can just keep up with that and not the language if they wish. Compared to the Python ecosystem. As Erlang inevitably grows in popularity, it too may fragment.
