Yes, I know the feeling, having had similar political BS affect me. In that case, you do indeed need to act in your own best interests. The act of divesting your interest will send a signal to them, which might waken them up, but from what you say, they would have to exit to keep the company alive and have others rebuild the company - which you indicate will not happen (broken promises etc). So manage your exit as best you can. Do not spread any bad words against them, it will look like sour grapes and might be actionable. The founder(s) might want to taint you in some manner after you leave, but the people in the business area you are in will not be fooled, they will lay the blame where it should go. Sadly, there are few ways to glorify an exit, especially if they crash and burn after you leave, so you might have to wander in the wilderness for a period before you get on your feet. Good luck with the process.
