I saw that too -- I think it's a typo in the OP, that the code is what they intended to recommend, and the comment is wrong.
Standard heroku Rails deploy instructions are to turn on `RAILS_SERVE_STATIC_FILES` but also to put a CDN in front of it.
My guess is this is what fly.io is meaning to recommend too. But... yeah, they oughta fix this! A flaw in an otherwise very well-written and well-edited article, how'd it slip through copy editing?
