You are quite wrong. An article consisting only of external links is not "fine" - it qualifies for speedy deletion under WP:CSD#A3 (No content). Your article contained only a single link to a company website, and had been like that for over an hour when I deleted it. People often put those in by way of advertisement, which is one reason why they are speedied.

What the guidelines actually say is:
WP:STUB: "When you write a stub, bear in mind that it should contain enough information for other editors to expand upon it. The key is to provide adequate context—articles with little or no context usually end up being speedily deleted."
WP:Your first article#Things to avoid: "A single sentence or only a website link - articles need to have real content of their own."
WP:List of bad article ideas #7: "Anything about which you are not going to write at least one complete sentence."
WP:Avoiding common mistakes: "Articles which are too short to have encyclopedic value. Articles must establish the context and notability of the subject. If an article does not contain enough content to classify it as a stub, then it may qualify for speedy deletion. Instead of creating a very short article, consider adding more content to the page before saving it, or using the  tag to indicate that the article is in the process of expansion."
