Great article but I don't really agree with their take on GPL regarding this paragraph:

> The spirit of the GPL is to promote the free sharing and development of software [...] the reality is that they are proceeding in a different vector from the direction of code sharing idealized by GPL. If only the theory of GPL propagation to models walks alone, in reality, only data exclusion and closing off to avoid litigation risks will progress, and there is a fear that it will not lead to the expansion of free software culture.

The spirit of the GPL is the freedom of the user, not the code being freely shared. The virality is a byproduct to ensure the software is not stolen from their users. If you just want your code to be shared and used without restrictions, use MIT or some other license.

> What is important is how to realize the “freedom of software,” which is the philosophy of open source

Freedom of software means nothing. Freedoms are for humans not immaterial code. Users get the freedom to enjoy the software how they like. Washing the code through an AI to purge it from its license goes against the open source philosophy. (I know this may be a mistranslation, but it goes in the same direction as the rest of the article).

I also don't agree with the arguments that since a lot of things are included in the model, the GPL code is only a small part of the whole, and that means it's okay. Well if I take 1 GPL function and include it in my project, no matter its size, I would have to license as GPL. Where is the line? Why would my software which only contains a single function not be fair use?
