I agree with the sentiment of every response I've read to your comment so far. The agressive tactics, paywall, general sense of sleaze all make me actively avoid following medium links.
But even ignoring all that, medium is the worst place for any article about programming because the code blocks do everything to make it harder to read them. There's no syntax highlighting, the lines wrap and the container the code is in pads the text to make a narrower column than the body of the article.
That's the opposite of what I want. Especially on mobile! It's one of the sites that make me wonder if its developers have ever tried using it.
