GPL is notoriously frowned upon when it comes to adoption in commercial environment (to a point where GPL licensed software is not allowed to be included in any way whatsoever). In that light I could see this as an attempt of a poison pill to prevent commercialization of their code by means of this "stigma" that is attached to the license itself. So a commercial entity cannot create an asahi alternative (or attach pieces of it to their own product) and charge money for it due to their legal dep telling them big no just because GPL is involved.
