I see 10 reviews not dozens and dozens and the ones I think you're referring to all have neutral status for the question "approves of ceo."

I think this is poor UI on Glassdoor's fault. "CEO Approval" on the page is not a statement, it is a yes/no question, with the empty circle designating No. (That's how I read it, anyway) It's especially confusing because the options just above and below it (Recommend, Business Outlook) use red X's to express disagreement, while this question does not, leaving the reader unsure if the commenter skipped this question or actively answered No.
