Is it true: Microsoft 'Halloween Documents' + embrace-extend-extinguish (1998-2002)?
Yes — this is confirmed.
Microsoft confirmed the authenticity of the Halloween Documents. The memos describe Linux and OSS as competitive threats and discuss protocol pollution tactics. The "embrace, extend, extinguish" phrase attributed to Microsoft VP Paul Maritz became a widely used descriptor of Microsoft's competitive strategy. The documents featured in EU antitrust proceedings (€497M fine, March 2004; €899M penalty, 2008) and in Comes v. Microsoft (Iowa, settled 2007). No factual dispute about authenticity or content remains.
