Barnes & Noble's complaints about Microsoft have accused the Windows developer of not just trying to be anti-competitive by discouraging Android but also trying to dictate what features Nook devices could use. Microsoft allegedly had "veto power" through prices as well as the terms of the license. It wanted control over what hardware and software features features the Nook was allowed to use, Barnes & Noble said, giving it a way to neuter a competitor by denying it any advantages.
