Interesting - i’ve read a lot of medium articles over the years on a daily basis, and not once it ever gave me an “upgrade” button. Maybe the writer can decide if it the article is free to use? I don’t know - but from my experience Medium is one of the more “open” platforms without any restrictions for the reader. Strange our experiences are so different.
This is the exact opposite of what I experience. Maybe we're in different countries(I'm in the U.S.) and they're targeting for upgrades based on location. Medium used to be a great resource, but now I loathe seeing it and I won't even bother clicking a medium link.
So could also be workflow related maybe. Or combi of both?
Maybe share a medium with “upgrade” link that I can visit and compare end-results?
