The fact that she was married to someone who did have hiring or firing power and WAS permitted in the office means she DID have (defacto) hiring or firing power.
I wonder what the ramifications are, legal-wise? Obviously the founder could be sued, especially if he was allowing someone who wasn't an employee to harass. I suspect A16Z will waste no time putting distance between themselves and the (allegedly) guilty founder. In the end, this wife's jealousy could end up costing her family 10s or 100s of millions of dollars.
