At a guess, the hilarity comes from the 'challenge' part. It makes it sound like Huawei is being challenged to do something different - which is pretty laughable by any standard the US intelligence agencies apply to themselves.

It is a bit like an Olympic athlete losing a race and seriously complaining that the competition trained too hard and challenging them to 'live a little more' (imagining that scene with a slightly miffed but condescending athlete cracks me up) - I mean, theoretically maybe, but the attitude that the competition should just give up is pretty funny.
