While I'm not defending the practice of vaporware, it's not the root of the problem here. The root of the problem is that if you have a policy of working unpaid overtime, unless you are lucky in finding only wise or scrupulous employers, your life is going to be trashed.
To you, it is completely irrelevant whether the reason your employer ordered you to trash your life was because the salesman sold vaporware, or because of the phase of the moon; the outcome for you is the same regardless of the reason the order was given. You have to change your policy of obeying such orders.
