I see the GPL as treating source code files closer to chess pieces, and insisting they remain in view.

What partisan pretensions are on offer with the GPL are unclear.

While a FSF member for decades, I take a syncretic view that the GPL is a crucial point on the licensing spectrum, and that economic value is maximized when there are products available across that spectrum for people to choose and use at will.

I guess, if we squint, this might be something of a political position, perhaps a libertarian one.
