Wow, those comments are really odd. Every time a WSJ article is submitted here a comment contains a link to avoid the paywall, and every single time people are grateful.
Every time there is also somebody complaining that we shouldn't evade pay walls at all.
But that's indeed a really odd set of comments. While there is some criticism on this thread here, it's way more down to Earth, nobody is talking about theft or anything.
Maybe people feel that people should only avoid paywalls in a random and haphazard way, and not a systematic way, or that people should avoid paywalls whenever they want but not make it convenient for the general public to do that?
Is there a name for ethical notions related to whether people make a habit of something, or whether people help make something convenient?
It is called "abusing a privilege" , and most elementary school children are taught not to take all the cookies from the jar just because they are invited to take one.
