The parent poster is implying that Activision itself believes Oneal is unqualified. That if Activision truly believed in Oneal, that she'd be president just as Brack was, rather than share the role.

Of course there are various examples of multiple leaders being successful, but that implies you trust Activision and Bobby Kotick to give them the opportunity to do right, which the poster does not.

I'll note that these posts are often written quickly, I'll agree that having two means someone thinks both aren't up to the task by themselves.

When you say: "I'm not saying they're unqualified"

its typically better to say nothing if you don't know (why are you telling us what you are not saying.). You're also not saying they are qualified.

I think what they're referring too when they say "One of them is a woman of course." Is pointing out an instance of the glass cliff.

Which it seems to be.

Great point. I think it depends on if the new execs view themselves as “creators” or “fixers”. Fixers can thrive in this situation.
