Medium is NOT a blogging platform, contrary to popular belief. Blogging is owning your content, and when you write for Mediium, make no mistake, it belongs to Medium. Although, I just switched over from Wordpress to Jekyll, and I find it there to be a lot less friction for publishing. I talked more about the new and exciting workflow of Jekyll at http://rmorabia.com/redesign I really don't agree with the author here.…
I invite you to glance over the Medium Terms of Service. "You own the rights to the content you post on Medium." https://medium.com/policy/9db0094a1e0f#0fae
"However, by posting or transferring content to Medium, you give us permission to use your content solely to do the things we need to do to provide Medium Services, including, without limitation, storing, displaying, reproducing, and distributing your content. This may include promoting your content with partner companies or services for broader broadcast, distribution, or publication."
(They do say they won't sell your content to third parties without your consent, which is good.)
And you don't control if and when the terms of service change.
