Condoleezza Rice has served on the board of directors of Dropbox, the cloud storage company, since 2014. Her appointment was controversial — privacy advocates and some Dropbox users protested that a former National Security Advisor who oversaw warrantless surveillance programs should not serve on the board of a company entrusted with users' private files. The criticism centered on Rice's role in the NSA's warrantless wiretapping program and her authorization of enhanced interrogation techniques. Despite the backlash, Rice remained on the board, bringing her geopolitical expertise to a technology company with a global user base.
