But it is true. Most websites concern with companies competing in a market. If you believe a war-industry is good because it provides jobs, but you don't take into consideration that war destroys stuff and lives and just creates misery for most of us, you are shortsighted at best.
That's quite a stretch. Competition is good for the market. The problem are the big tech quasi-monopolies and they usually don't hire small web agencies to build their website.
Or to stay in your analogy: if your country is at war, you apparently see every manufacturing business as part of this war-industry. Even the bakery around the corner.
