This is really sad, not only did they copy your idea, not paid you anything (yeah, some kind of azure credit is not really costing them anything) nor gave you credit, they wasted your time and gave you a humiliating silent treatment. At a smaller company I tend to think that wouldn’t have happened but Im not sure to be honest. I hope that you get the credit and end up in the place you deserve to be. I wonder if Andrew is an a-hole or he really just couldnt do anything about it, it is possible that they didn’t want to remunerate you for legal reasons, in the sense that you could have asked for more later on. But no credit? I think Andrew may be as I first thought
