It's so common on HN to see people argue law and policy and then generalize it to make an argument. They didn't say unprofitable companies shouldn't exist, but there's certainly a case to be made that large companies swooping into a market, reducing their prices to squash competition and then raising prices is not good for consumers, and there's governments that make this practice illegal. Intent matters.
