"A new campaign, Showusthecode.com, requests every leader in the Linux world, and companies invested in Linux, to stand up and demand that Steve Ballmer show the world where Linux violates Microsoft's intellectual property. He has been making these claims since the Novell-Microsoft deal. If Microsoft answers this challenge — by May 1st — then Linux developers will be able to modify the code so that it remains 'free' software. If such infringing code doesn't exist, we will have called Microsoft's bluff. And if the campaign garners enough attention and if Steve Ballmer maintains silence, then the community and companies behind Linux can take the silence for for the admission that it is."
