It sounds like Mr. Corbet is fine with the occasional link as long as people keep LWN's business model and financial needs in mind. LWN is an excellent resource, I highly recommend subscribing.
Who is "we"? There's been numerous threads in LWN posts that state that posting subscriber links to hackernews is in fact encouraged by LWN. So you seem to be stating the reverse of what is general knowledge.
'The following subscription-only content has been made available to you by an LWN subscriber.'
Are those really only subscriber links?

sounds like he is fine with it as long as it comes with subscriptions, which makes sense. Maybe my suggestion should have been to subscribe and I wouldn't have been flagged. :)
