We're way off topic, but we're not disagreeing here. If there was no misrepresentation involved then there's nothing unethical. I've edited my reply to specify. As to who gets hurt (assuming information asymmetry): the users who depend on the service, the buyer that loses their investment, and the employees that put a significant portion of their lives into trying to breathe life into an operation where the founder was only interested in creating the short-term appearance of value in order to flip it.
