In February 2008, Power.com raised an $8 million first round from Draper Fisher Jurvetson and Esther Dyson. When it started to deploy its system on Facebook a few months later, the social net asked it to cease and desist. Facebook said Power.com agreed to stop including Facebook users in its services, though it pleaded for time to wind it down. Power.com said it had no such agreement. Facebook claimed that Power.com sent Facebook users a message meant to look as if it came from the social net’s administrators, asking them to share their data, and so, Facebook filed its suit.

Asked to comment on Power.com’s legal action, Facebook rep Barry Schnitt called the company’s claims “baseless,” adding, “we will fight them vigorously, while continuing to pursue our initial complaint to protect our users.”
