Originally said "coming soon" to see if anyone was interested. Turns out they are!
It's the same idea as setting up a landing page for a product that doesn't exist and seeing if people click "pricing" or "buy now" to determine if there is a market for it.
(Sorry, don't mean to attack anyone or put too much blame, but let's call it what it is.)
To get back to our argument: By the time you said "coming soon" you didn't know if it was coming at all, so I would call that a bit of a lie.
