I don’t think it applies at all. The basis for the tolerance paradox is that intolerance harms others. While using permissively-licensed software in proprietary products certainly omits benefits to others, it can hardly be argued to be harmful.

In other words, the intolerance paradox relies on people agreeing that “harming others is always evil”. While applying it to copy-left relies on people agreeing that “non-reciprocity of good is always evil”. I’m sure some people think that way but I doubt most people would.
