These articles kind of miss the appeal of something like medium. If you have a blog and/or an audience, you probably don't want to use medium very often; but if you have something to write that you think might appeal to a broader audience medium might get you more publicity.
I mean, if you have your own blog, why write an op ed for the New York Times? Why write a comment on HN? Why do a TV interview? Why write or speak anywhere but your own website? Because many of those [ah, fuck, how do I choose another word than] media can reach a bigger or different audience than your website, spreading your ideas, increasing your reputation, etc.
The other nontrivial factor for medium specifically is for people who want to write something every few months or so. They're unlikely to build an audience for their own blog, but if they write on medium they might get read.
