I haven't used Phoenix or Elixir since the latter was new, though I'm sure that they're great tools. The fanaticism around them partly comes from disillusionment from frontend development. The pendulum has swung to "server-side was right the whole time!" Disillusionment with Ruby may also be a factor as well. Elixir also makes way more promises around scalability and fault tolerance than any language I'm aware of (yes I know it's using the Erlang VM but no one wants to write Erlang).
