The web is a public forum, and it makes no sense to us when a company to post information on it and then whines when people provide links directly to that content. All a link does is tell where something is, under the hood it's up to the browser to do something with it, so it's not even like there's functionality behind it.
That said, did an article help you out? If so, link to it! You don't have to link to the site's main page, go straight for the article URL itself.
Afterall, what's the point in having a site supporting Linux and software development if you can't share it with the community. Help other users benefit the same way you did.
