I'd certainly investigate the entire corporation. If the guy is abusing his position of authority (which means that any "consent" given is a fiction) and the employees actively support this, then there's a good chance that the behaviour is rampant in the company.
There is, however, a flip-side. He's undoubtedly led the company to produce some superb products and has pushed them in a well-identified direction. Far more so than virtually any other US corporation. There's very obviously something about his personality and mindset that is actually wanted to have a successful business, and this something is lacking within much of the western business community.
Basically, much of the western world is stuck in Harvard MBA Land, and companies operating under such principles invariably collapse from complete incompetence. They're popular because those with MBAs are usually brash, arrogant, controlling, dominant, and abusive - typical sociopathic traits - and sociopaths in the boardroom tend to be very good at producing stable management structures and very high stock returns. Just not successful busineses. But who cares, if you get rich?
This does not mean we need more sex offenders or Chinese spies running US megacorps. It means we need to find out exactly what in his attitude allowed him to identify successful patterns, we have no reason to want or desire any other aspects of the guy.
