Charles O'Meara in Bye explains why he will no longer publish on Medium:
You’re known by the company you keep. You may be a very nice person but if you decide to join Hell’s Angels and dress like a biker, don’t be surprised if people start judging you.
I did not even know about this »loud« audience that Medium has because I usually read the article and immediately leave the site again, but it seems not a nice place to be in. He ends with:
I don’t need this … to have ‘presence’ on the web
That's what I like most about his action. He does not stop publishing, but he starts to do it from his own site. No middleman that benefits from his content.
