Drummond's departure note declined to reference or acknowledge these allegations. Drummond has been central to Google and Alphabet's story. As a partner at Wilson Sonsini Goodrich & Rosati, he drafted the initial incorporating documents for then-startup Google. During his tenure, Drummond oversaw a number of high-stakes litigations against the likes of GEICO and Microsoft, and also shepherded acquisitions of companies that are now seen as essential to Google, including YouTube and Android. The departure also comes alongside Google co-founders Larry Page and Sergey Brin's decision to step back from leadership roles after 21 years at the company. Drummond will not receive an exit package, unlike some other recent executive departures. However, he did sell $222 million in stock, most of his shares, since late last year.
