1. "told by the advisor that if someone gets an advisor he cannot refuse their advices" This is ridiculous. An advisor gives advice and does not dicatate. You can always fire an advisor (but don't do so out of personal grudge). 2. "supposed rockstar to be hired as product engineering manager is the son of the advisor" In Silicon Valley (and general US business practice), this is called "conflict of interest" and is generally considered unethical. He should have "recused" himself from this topic. If I were to fire the advisor, it'd be for #2 and not necessarily for #1 (for #1, I'd just have a good laugh and perhaps tell him that the era of Franco is over). 3. "I got a confrontation with the rest of my board (founders and advisor)" However, you might ask why the other founders (not the advisor) think it's a good idea. ¡Suerte!
