FYI: the owner of lwn.net is on record as being ok with people widely sharing subscriber only content links.

LWN links are intentionally shareable. See the "Welcome .." box at the top:

> The following subscription-only content has been made available to you by an LWN subscriber.

When (as a subscriber) you make such a link, it says that if such links are "abused", the ability to make them may go away. Having the occasional article posted to HN seems to be OK with them (or they probably would have added a specific request not to post them to news aggregation sites). It's likely a wholesale "Free LWN for all" page with a weekly subscriber link to all the articles they're worried about.

right below that it says "The following subscription-only content has been made available to you by an LWN subscriber."

feature, not bug

Nope. LWN built the feature that subscribes can share links as a feature. If you subscribe, you can share.

LWN is a very fair and ethical organization. This struck what felt to them (and to much of the community) as a good balance.
