"The viewpoint expressed by Wellnhofer's is understandable, though one might argue about the assertion that libxml2 was not of sufficient quality for mainstream use. It was certainly promoted on the project web site as a capable and portable toolkit for the purpose of parsing XML. Open-source proponents spent much of the late 1990s and early 2000s trying to entice companies to trust the quality of projects like libxml2, so it is hard to blame those companies now for believing it was suitable for mainstream use at the time."

If the license says one thing, and you say and promote something else, you can't say "But it's in the license" and "I said so at a conference" just as it fits you.

So what should I believe? What you write in the license? What you say at a conference? Nothing you say?
