"its not bad low quality product, its shit noone would ever want to touch with a pole, HARDLY TO PAY FOR" - then you got your answer, if you are doing thing which nobody needs or no one wants to pay for it, just leave. But consider the fact, you are tech-guy, for many tech-guys some products may seem useless, but there are lots of people who may pay for it and use it everyday. Saying "leave your job" is very easy, because as OP I am not leaving my job, you are going to leave. think about cases, eliminate best cases if they are unrealistic. - best case: top management says: ok, seems you got it right, lets make product as this guy said. - worst case: you leave your job - something in the middle(1): you will make that shit happen, you get salary for it, if product fails you leave - something in the middle(2): same with above, but you don't leave, you try to make product better - something in the middle(3): you fight for better design, better product, present your arguments, show people that you know more about product, about market than any other managers, so they may consider your facts
