“Who ordered that?” is a pretty famous question in particle physics. I think the commenter is just asking “who ordered neutrinos”? It’s a good question, even if it’s not formally rigorous.

That (which was about muons) was about the muon not being predicted. The neutrino was predicted (to explain missing energy in beta decay).
Great. So we have the following:
Q. Who ordered neutrinos?
A. They're necessary because they carry energy away during beta decay.
Is the Q there a made up historical quote? Why, yes it is.
