By doing this, Microsoft is violating not only Google's service terms but also the Linux trademark owned by Linus Torvalds, sublicensed to Linux Español in the Spanish territory. In addition to that, the actual advertisement links to a false Case Study where it is stated that Tommy Hilfiger saved money by migrating to Windows. This case study might be true in other countries but its false and therefore illegal in Spain since the website in question is hosted in Linux/Apache/OpenCMS.
This has been reported to the Comisión del Mercado de Telecomunicaciones, Secretaría de Estado de Telecomunicaciones, Jurado de la Publicidad and Ministerio de Industria.
Google Spain has also admitted that the advertisement should be stopped and has forwarded the case to Google Inc. The team at Linux Español is currently in contact with Google Inc and truly hopes this abuse will be stopped soon.
