Sam notes an Ars story on Microsoft pulling the Windows 7 USB/DVD Download Tool from the Microsoft Store website after a report indicating that the tool incorporated open source code in a way that violated the GNU's General Public License. Whether the software giant is actually violating the GPL, a widely used (including by the Linux kernel) free software license, is not confirmed. 'We are currently taking down the Windows USB/DVD Tool from the Microsoft Store site until our review of the tool is complete,' a Microsoft spokesperson told Ars. The fact the company pulled the tool doesn't bode well, so we'll have to watch closely to see what the company puts back on its servers.
