After reading the terms of service I found nothing saying anything like this. Maybe I missed it. Can someone point this out in the TOS.
I did find this under item 4. Use Restrictions
(xxvi) infringe and/or violate any of the Terms (xxvii) in connection with Contributions, upload and/or store on the Site continuous integration artifacts or nightly builds, (i.e. you may only upload and store content in direct connection to official software releases).
The keyword is CONTENT as defined below.
The Site also provides you with additional resources such as blogs, public forums, including any other content related thereto such as contact information, videos, text, files, logos, button icons, images, data compilations, links, other specialized content, technical data, documentation, know-how, specifications materials, designs, data, the “look and feel” of the Site, algorithms, source and object code, interface, GUI, interactive features related graphics, illustrations, drawings, animations, and other features available on or through the Site (collectively, the “Content”).
Edit:
Under section 2 The Site
they define Platform as various types of files, they also define a contribution.
