I strongly agree. I have a (mostly) link blog [0] (for which I wrote the SSG [1]) and do link to Medium articles but am getting more and more tired by the nag-screen that shows up every 5 or so posts after having deleted the medium cookies (again). I guess there is an extension for that, but I am too lazy to install it :-) But a bigger question is for those who publish on Medium: how many people get scared away daily from your articles after hitting the sign up nag screen?
