Why would you say that?
I once had an engine destroy itself at 58,567 miles on a 60k warranty. I didn’t feel bad that they honored their warranty and replaced the motor.
After all - that is what I paid for. And so did he.
“Why would you say that?”
Because your motor still was under a legitimate warranty. If you hadn’t had it replaced you would’ve been wrong.
Your buddy’s TV was over 5 years old, and most likely not under warranty (you never said). He took advantage of a seller’s generous — and very stupid — return policy, and technically he wasn’t wrong. He was running a scam. A decent person would not have done that.
But if you can’t recognize the ethical problem here, well ... what can I say?
