+# WTFPL is a terrible license
+
+The use of WTFPL as a license is discouraged for multiple reasons.
+
+* **No Warranty disclaimer:** This could open you up to being sued.<sup>[1]</sup>
+* **Swearing:** This prevents settings like schools from using your content.
+* **Not OSI Approved:** Same as public domain?
+
+The Open Source Initiative chose not to approve the license as an open-source
+license, saying:<sup>[3]</sup>
+
+> It's no different from dedication to the public domain.
+> Author has submitted license approval request – author is free to make public domain dedication.
+> Although he agrees with the recommendation, Mr. Michlmayr notes that public domain doesn't exist in Europe. Recommend: Reject.
