Microsoft misusing copyright law in Xbox antitrust lawsuit, group says
A consumer-protection group says Microsoft is misusing the Digital Millennium Copyright Act (DMCA) in its legal defense and countersuit against Datel Design & Development, which alleged antitrust violations after the software giant locked out unauthorized Xbox 360 accessories.

According to Microsoft, the Digital Millennium Copyright Act (DMCA) gives it the power and the legal authority to remotely disable Xbox 360 compatible memory cards, controllers and headsets that were not made exclusively by Microsoft or one of its affiliates.
As you might imagine, it hit the fan in 2009 after Microsoft issued an Xbox 360 firmware update that blocked a less-expensive and non-Microsoft-made memory card from working on Xbox consoles. Third-party accessory maker Datel Holdings then sued, calling the disabling of memory cards a deliberate anti-competitive move
