The document is an application for leave to file an amici curiae brief in support of appellant Yelp, Inc. in a case before the California Supreme Court. The application was filed by several technology companies and non-profits, including Change.org, Engine, GitHub, Medium, Patreon, SiteJabber, and Wikimedia Foundation.
