I think this discussion may have run it's course, as I think both sides have expressed their views. I have a few closing comments. If there are next steps, I think it's really up to Ton and the Blender Foundation to consider and propose them, because it is likely only through their action that something would occur.

Is there some company that could publish a case study about how they feel it safe to build closed-source extensions to GPL code? In my experience, closed-code is not allowed to link to GPL code, because of the GPL would then require the closed code to be under the GPL. The issue of it being allowable without distribution is not useful, because distribution to contracting shops and other third parties is typically necessary. Further, a 3d modeling tool can't be adopted at a game or VFX company without this ability to link with closed source. Yesterday I shared the details of this topic with a friend in engineering at a major game studio (which I'd prefer not to name). He re-confirmed what I've heard many times from him in the past on this topic. Aside from the other issues that affect their choice of 3d modeling tools, in his opinion they would be unable to even consider using a tool that they couldn't safety link with closed source. Blender is an incredible tool for Internet hobbyists, education, and open-projects, and it will remain an incredible tool for those situations whether this issue is addressed or not. Further, industry tools are so far ahead, and community lock-in is so pervasive, that even if this issue of safety linking with closed-source was addressed, it still would be an uphill battle for Blender to make headway against Maya, Max, Houdini, or custom developed in-house tools (something Blender once was!). This same pattern is evident in the GIMP community, where despite having tried to address linking with closed-source, it's still not a serious alternative to Photoshop for most companies. That said, I think it's important to consider whether it is a goal of Blender to be a "professional" 3d tool that can compete in the community against Maya, Max, and others. If the answer is "yes", then I believe we must enable linking with closed-source extensions. If the answer is "no", then Blender can freely proceed to be the best open-source-compatible 3d modeling package it can be. I believe it is false-hope and a mis-alignment of goals and action to believe that Blender can make any headway in the professional 3d community without enabling the ability to link with closed-source. _______________________________________________ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers
