With this license, Medium can bind all your blog posts into a dead-tree book, put your name on the cover in giant font, sell it in Barnes and Noble, and give you not one cent for it.
Now let me edit this a bit...
"You give Medium a non-exclusive copyright license to display your content worldwide."
Thanks for the link. The issue is discussed repeatedly in that thread, and according to some posters the "license" they want is needed to show the content on their site in the first place. Interesting.
Still. The company that manages my server has no terms like that. It's all my responsibility, to roam all of freedom-land until I'd reach a border called the Law, with no lecturing on rules in-between (if you read around the terms & service page)!
Your VPS provider is operating according to common-carrier provisions. It's a bit like the postal system, or safety-deposit boxes--since you manage the software, and they only handle things as raw disk blocks/IP packets and below, they don't need a license to them.
