I think that the objective is a market study, for which I believe there are some tried and tested methods, although it occurs to me that in this field those may not apply as so many other things, however if that is the case, then I believe "how to find out what the users want without selling vaporware/other questionable tactics" is a worthwhile problem to tackle in and of itself.
Selling vaporware is to me similar to using users as unwitting beta testers, I don't believe in it, I think we should be upfront like the examples you cited: if it is a beta let people know, if it is vaporware, let people know, if it is a demo, let people know.
When I say fake sell I mean do the transaction then provide a refund.
In my opinion it's the ethical thing to do, not just for you but for your users. Why bother creating a product if it's never going to get traction in the market? You won't be able to afford to support it well, and it won't develop into a great business unless you get significant revenue. This is more unethical for the users, as you'll have to fold or let is stagnate. Why risk it?
Time is a valuable resource. Wasting people's time with a marketing survey under the guise of a product offer is not my idea of ethical. I would fly off the frickin' handle if someone wasted my time for me like that, using a deceptive little trick like that.
