If people are disappointed that they can't actually buy your product, it's only because they want it and can't readily get it by any other means (otherwise they never would have bothered with you in the first place). By validating your idea, you move one step closer to satisfying their wants and needs. If you don't validate your idea, or validate by a slower or less effective method, you are delaying, possibly indefinitely, their ability to purchase what they desire. While some people may react negatively to being "misled" like this, that doesn't change the fact it is objectively in their best interest. Your desire to avoid misrepresentation does no good beyond making you feel better about yourself for having followed an arbitrary moral rule without regard for circumstance. Any ethics system that says go against everyone's best interests to make yourself feel good is dumb.
