2. Being an arrogant jackass is not grounds for termination. Have you paid attention to business news lately?
3. Sorry if 4 points constitutes too "much" for you.
Regardless, you're overthinking a very simple matter. And no, being an arrogant jackass isn't ground for termination unless that trait leads you to make comments that reflect poorly on the company you work for.
This isn't an uncommon thing. I worked for a newspaper once and all employees (from pressroom to editorial staff) had to sign an agreement that any behavior outside of work that risked reflecting badly on the paper or damaging its image or credibility would be grounds for dismissal. I saw several people let go for that for things you wouldn't think would matter. One guy was fired because of a domestic dispute where the cops were called to his home. One guy for a DUI.
You think Apple wouldn't have those same standards for their employees and execs?
