He's a polarizing figure. I know people who used to work in Social (and elsewhere in the company) that hated working for them, and now they don't work in Social. I also know people in Social who really admire him as a visionary leader who's not afraid to take a lot of personal flack to get the job done.

I think this is common to many people with strong opinions and the confidence to act on them. Marissa was very similar: some people absolutely hated her, while others really respected her.
