Looking at the mess that's software licenses, I 100% get the "fuck this" approach to dealing with them :) that being said, this license has some issues, specifically with warranty, the vague language of the terms grant, and the fact that "public domain" licenses don't really legally exist in various countries. All of these have led the FSF and the OSI to reject it as a good open source license, and also led to companies not being able to use it for silly, but unfortunately real legal reasons (I don't work there, but Google is one clearly documented example).

Would you consider moving the library to a more established license that's just as free? It could even be the Unlicense, which is public domain but with a "more legal" fallback way of saying "do what you want".
