Gillette was scared of DSC they started up Gillette Shave Club. That didn't work so they started attacking DSC in their ads which only helped drive brand awareness of Dollar Shave Club. Its seems they finally just gave up and sued DSC on patent infringement on a razor they don't even manufacturer.
Also no VC backed company is going to be profitable if they have VC money sitting in the bank. It was less than a year since DSC raised cash.
