Windows7 usb/dvd tool recruits people to suspend downloading

Windows 7 USB/DVD Download Tool is Microsoft's system installation disk production tool for netbooks in October, which can be used to easily copy Windows 7 installation files to U disk or In the DVD, it is convenient for further installation of the system.
But in the previous version, because Microsoft "carelessly", quietly adopted the source code of the open source project ImageMaster of GPL license, but did not disclose the source code of its own software, thus causing many doubts about the software. In this case, Microsoft officially apologized and suspended the download of the software.
Recently Rafael Rivera has found evidence that Microsoft's Windows 7 USB/DVD Download Tool may have stolen the source code of the open source project ImageMaster licensed under the GPL. The GPL code is a widely used free software license that is usually hard-wired in open source software. Although this code is free to be used, it has its own terms, such as sharing "any changes made to the code".
A Microsoft spokesperson has confirmed that Microsoft has suspended the Windows 7 USB/DVD Download Tool. In addition, Microsoft has begun to investigate and investigate this issue until Microsoft's investigation is completed.
This powerful Microsoft will have an event that has been exploited by the GPL code. Isn't the trend of "learning" more prevalent?
