Last I checked (not super recently) there was a login wall that popped up after you’ve seen X articles that the authors have chosen to put behind the login wall. Also, if an author wants an article to be eligible for inclusion in aggregated publications, they have to put it behind the login wall. It’s quite possible my info is outdated; happy to learn what the current state of affairs is if things have changed.
