It's not hard to find earlier examples where the phrase is used to describe enabling and (yes) leveraging community contributions to accomplish things that otherwise wouldn't be practical; see my other post for a couple of those.

But then people will rightfully object that the term "Open Source", when used in a capacity related to journalistic or intelligence-gathering activities, doesn't have anything to do with software licensing. Even if OSI had trademarked the phrase, which they didn't, that shouldn't constrain its use in another context.

To which I'd counter that this statement is equally true when discussing AI models. We are going to have to completely rewire copyright law from the ground up to deal with this. Flame wars over what "Open Source" means or who has the right to use the phrase are going to look completely inconsequential by the time the dust settles.

AI may make copyright obsolete, or it may make copyright more important than ever, but my prediction is that the IT community will lose something of great value if the term "open source" is diluted to include licenses that restrict usage, restrict distribution, and restrict modification. I can understand why people may want to choose somewhat restrictive licenses, just like I can understand why a product may contain gelatin, but I don't like it when the product is mis-labelled as vegan. There are plenty of other terms that could be used, for example, "open" by itself. I'm honestly curious if you would defend a pork product labelled as vegan, or do you just feel that the analogy doesn't apply?
