I appreciate the sentiment and intentions that Jarsve has in creating the Microsoft petition.  While I don't think this has any chance at all (sorry to be a pessimist), I feel that he would appreciate a native English speaker to express his appeal to Microsoft in terms that may attract more interest from both Sonar users and Microsoft.  As a rare contributor to this forum, here's my opportunity to post...  I've given my own translation/interpretation of Jarsve's text, with an increased slant toward why Microsoft might consider this at all. 
Jarsve... I hope I have expressed your intentions accurately (and by the way, good job on the English... I respect your effort very much.)
 
Note: I'm not interested in debating the language or promoting this myself... this is my donation to Jarsve and the forum to use, edit, or ignore as you all wish...  I don't feel strongly enough about this to push it myself, but I don't mind giving this to someone who wants to try.  Good luck.. and even though I am exploring different DAW's, I would sign this if asked.   Here it is:
 
Dear Microsoft,
 
The Cakewalk Sonar user community is surprised and upset by Gibson’s unexpected announcement that they will no longer develop this capable and respected audio production software.  Sonar users are passionate and loyal supporters of their favorite DAW (Digital Audio Workstation) as the best tool to express their creativity on the Microsoft Windows platform.  This software has a documented history of innovation and evolution, from its early roots in MIDI sequencing to being one of the most comprehensive audio production packages available today.  Sonar customers are very proud of the many exclusive and “first-available” features that demonstrate impressive and progressive development in recent years.    Some examples include early adoption of 64-bit architectures, ARA implementation, and the ProChannel user interface that is favored even as competitors are learning to emulate its appeal.  Since Sonar users are also aware of Cakewalk’s close collaboration with Microsoft on advancing music production technology, the undersigned on this petition ask for your consideration.
 
With the future of Sonar development in doubt, please consider adopting/acquiring Sonar as a new Microsoft branded DAW.  This idea could bring an abandoned user community into a new era of Sonar development, while also solidifying Windows as a desirable music production platform for a new generation of music makers.  The Sonar line is already geared to support all user types, from beginner hobbyists through professional production studios.   
 
Although music production may not represent a significant portion of the Microsoft customer base, the Windows platform has not yet earned a first-choice reputation among many in the artistic community, and it seems recent Microsoft advertising has shown interest in changing that. 
One logical solution is to provide the artistic community and all Microsoft Windows computer users a default place to start their musical journeys.  Tighter integration with Windows and access to Microsoft resources would enhance stability and reliability even further to retain and attract customers that want to make music with Windows.  Existing Sonar users would be drawn in by application familiarity and compatibility with their years of past Cakewalk/Sonar project files.  New users would be drawn in simply by their musical curiosity of this "new" Windows feature and the ability to explore the music they want to make from within the Microsoft family of products.
