Not really. Google owns the copyright for all code contributed by Google employees on Google time, and currently they are the only copyright holder [1]. In order to contribute you have to sign the standard Google Contributor License Agreement (either [0] or the corporate version) which gives Google a perpetual irrevocable copyright and patent license. Since the project is BSD licensed anyway, unless you're contributing something you intend to patent, you're giving Google nothing by signing the CLA: you still own the actual copyright. (Based on my skimming the agreement; IANAL) [0] https://cla.developers.google.com/about/google-individual https://cla.developers.google.com/about/google-individual [1] https://github.com/upspin/upspin/blob/master/AUTHORS https://github.com/upspin/upspin/blob/master/AUTHORS
