I'm never sure if I like or hate when a site's adblock/article limit/sign in requirement etc is so easy to circumvent.
On the one hand it's good for me, on the other I feel like, couldn't you have put in a bit more effort? if you're going to make it that easy why bother?
(I know it's just because most people don't realise)
I use the excellent Readium bookmarklet[0]. Drag it to your bookmarks bar and whenever you encounter a Medium article you can't read, just click it and problem solved.
