The quality isn't the (main) point, it's the supply-chain relationship. Suppose our Raccoon finds a fan in the dumpster. Standard electric consumer grade fan. It might even be a really nice not-garbage fan. It's just been put out free to take on the condition that there's no liability or guaranteed support. If the Raccoon uses the fan as expected; For personal cooling purposes. There's no problem. If the fan breaks, the original creator says "WONTFIX", the racoon is a little sad but all is fine in the world. Suppose instead our Raccoon runs a major aircraft manufacturing company. If it were to take this fan and use the fan blade for a turbojet engine. The fan breaks now, a plane crash-lands and people are injured, the big company insists that it be repaired immediately. The original creator says "WONTFIX", and the company's VP of security is outraged. "Do you not understand how serious this is? The fan is used in a major airplane, you must fix it. It's no longer a hobby, you're part of our supply chain!" Now obviously, were Raccoon-Boeing to use fan blades from consumer fans put out on the road free-to-take, there'd be mass outrage. Obviously the person who gave away their fan isn't liable for the misuse of the thing they gave away. They owe the company nothing. If anything there'd be riots in the streets about the Racoons being this reckless. So why do we let software firms get away with this?
