> Outsourcing a doc to a SaaS seems like something I would never do if I cared about the product/software.

I'm inclined to agree, however I could see the argument for it if you are printing money (so even something expensive like readme.io [no affiliation] is inconsequential) and you've got something in place to keep everything up to date, and the docs are well integrated to your new engineering hire onboarding.
