No, the lawsuit is from authors who don't want their work packaged and sold by someone else without compensation. You understand that by your position, i.e., that the GPL is invalid, that since Monsoon doesn't have ANY license to use or modify the code, that the authors can essentially claim every dollar of Monsoon's revenue.
Your logic would also invalidate end-user license agreements. If that happened, there's nothing stopping me from repackaging Windows and selling it as kevkromOS at 75% off Microsoft's prices.
My logic is sound and proven by your own posts: software released under Stallman’s license isn’t “free” even if they tell you it is. Use BSD licensed code instead and you can avoid copyleftists.
