I agree they should have done what they said they would do and should have talked to potential customers before making something that was not wanted or needed.

I agree they should have done what they said they would do and should have talked to potential customers before making something that was not wanted or needed. And I do not dispute what you say about the product not being needed. I also agree that the money would have been better used on other companies but personally I think that the employees are the losers here (as are the investors). If the employees truly believed in their product then the employees have worked on something that has gone nowhere. All their work and effort is gone. That cannot be regained. These people are out of work. And for that reason, it is sad.
