I think your answers to these questions have a lot to do with your career goals. If you don't have an interest in being an academic, then I'd definitely jump ship and do something where progress is tied to revenue (i.e., business). If you do want to be an academic, then I'd work hard to make the best out of what seems to be a pretty frustrating situation. You can still redeem this experience through networking, running side projects, publishing etc. Those are all things that will help you if you choose to remain in the academy.
