It's a number of articles per month limit.

Open it in an incognito tab.

Medium apparently allows X many reads for per month for certain account levels. Somehow this policy seems more petty, vicious and stupid than honest to gawd paywalls.

Medium is just blogging site. Boycott it. It's awful. Wordpress or whoever just has adds.

It's not paywalled for me.

Medium has this policy that you get a certain number of free articles views per day or something. It also sometimes blocks certain browsers, but this I am unsure of.

You’ve probably viewed another article or 2 on medium. If you open in a private tab the paywall will likely not be there.

Paywalled for me too. It's ridiculous to use Medium for corporate content at this point. This company has paywalled a front page HN story.

I think the writers decide if it is paywalled (if it is they get paid). Still would prefer just having ads but I guess adblock is too popular for its audience.
