Medium.com is absolutely rotten for this behaviour.
Not only putting the soft, "sign in to view" but then on some articles requiring a full hard paywall... But you only know this after signing in.
I'm not entirely against charging for well written articles; good writers deserve compensation, but don't tease me, make me jump through a hoop only to find there's another much higher hoop sitting beyond it.
I’ve just cancelled my Medium subscription. I was finding myself going there less and less. So many articles saying the same thing in various levels of broken English.
Libredirect doesn't check and update working instances, if I recall correctly with libredirect you have to manually add instances to the list and can only ping the provided ones manually
There's a few userscripts on greasyfork for it as well
You can also use farside on browsers that don't support userscripts just by modifying a url
It has been particularly useful for browsing reddit pages without actually going to reddit because I'm not going to give spez my data and libreddit instances sometimes max out on requests so I just have to close and open tabs until I have a working instance
