Just because you don't have access doesn't mean that people with access should be disallowed from discussing it. It just means you can't really discuss the article, but that's never stopped anyone from commenting before
There are plenty of posts every day that don’t require you to get through a paywall - I personally just ignore them. I imagine there are only a handful of paywalled articles a week, and most of them end up having an archive link in the comments anyway
It is funny how things that were completely ordinary 100 years ago are now considered luxury items. I suppose it's because we don't use them for the same purposes (previously transportation and as "work horses") and because feeding/housing/mucking is now a burden for city/suburban dwellers.
