I came across GIMPShop.com which distributes an installer for GIMP bundled with some kind of adware:
Gimpshop.com is distributing the original unmodified software, obtained directly from GIMP's repository website, and does not modify it in any way. These installers comply with the original software manufacturer's policies and terms & conditions. DownloadAdmin™ is an install manager, which manages the installation of your chosen software. In addition to managing your download and installation, DownloadAdmin™will offer free popular software that you may be interested in. You are not required to install any additional software to complete your installation of your selected software. You can always completely remove the programs at any time in Windows' Add/Remove Programs.
There is a "GPL" page on the site:
and as far as I know the installation will include this as required. I have not attempted to request the source code from them.
But it seems to me that it conflicts with the terms and conditions page:
GIMPShop T&Cs page
- Use License
a. You can only download one copy of the information or software on Gimpshop.com. The download should be for personal, non-commercial transitory viewing only. This is not a transfer of title, however it is the grant of the license. If you have this license you may not: i. Modify or copy the materials...
Now, presumably they are referring to their installer here and not to GIMP itself, but it seems very vague to me.
Is this a violation that I should report?
