 The Unlicense software license, published around 2010, offers a public-domain waiver text with a fall-back public-domain-like license, inspired by permissive licenses but without an attribution clause.In 2015 Github reported that approximately 102,000 of their 5.1 million licensed projects, or 2%, use the Unlicense.The Zero Clause BSD license removes half a sentence from the OpenBSD template license, leaving only an unconditional grant of rights and a warranty disclaimer.
