I have foregone our take home for exceptional candidates, but let me ask you, do you also demand compensation for in person or zoom call 1-1 interviews? Surely thats the same time of your life.
Being told "here do this arbitrary thing that will take 4 hours of your time and maybe we'll look at it, and then if we even bother to do that, maybe we'll respond" is different than an interview where both parties invest their time face-to-face.
