What? Medium can take your content and use it for an ad or syndicate in any way they want without compensating you. Yep, all that hard work writing great content and Medium gets to reap the benefits from it. And they delete your license the minute you want to delete your content.
So the moral of the story is “read the fine print on everything.” Especially when it comes to your content.
