Honestly, though, if LWN was worried about this, they could put some sore of limit on the number of times a subscriber link could be used (per time unit?) or something. I don't think they are, and rightly so: the exposure to their content (which is very good value for the small amount of money they ask subscribers), as well as their liberal policy on these 'friend links' probably lead to more subscribers. Personally, I want to read the LWN articles when they appear there (on their RSS feed, to be precise), and not when someone gets around to posting a link on Hacker News.
More seriously, LWN articles get posted here quite often, and the exposure probably encourages more people to subscribe. I always assumed that was the point of allowing people to create these links to subscriber articles.
LWN subscribers can create sharable links to articles that are not yet generally available to non-subscribers. People coming in via those links are allowed to see the article. That's what is happening here.
"The following subscription-only content has been made available to you by an LWN subscriber. Thousands of subscribers depend on LWN for the best news from the Linux and free software communities. If you enjoy this article, please consider subscribing to LWN. Thank you for visiting LWN.net!"
At first glance it seems that they don't actually object to the article being shared.
To quote from LWN's FAQ: "Where is it appropriate to post a subscriber link? Almost anywhere. Private mail, messages to project mailing lists, and blog entries are all appropriate. As long as people do not use subscriber links as a way to defeat our attempts to gain subscribers, we are happy to see them shared."
So if you like this article, subscribe to LWN. I did!
