Other times, though, it can be disastrous. Every time a startup goes out of business because it “couldn’t get traction” or it didn’t “go viral,” there is an excellent chance that there simply wasn’t enough demand for the product because the product didn’t solve a big enough problem for its market or it didn’t solve the problem in a way that worked for users.
Doing this is just another way to offload responsibility, pass the buck, etc. "Well, I was only building what the users wanted---blame them!" If people really knew what product they'd like best, they'd build it for themselves, maybe.
