Maybe there's zero business value in keeping secrets (I don't believe that at all), but even if that were the case and Apple were just overly obsessed with "the prestige" [1][2], why would that change anything? They should be free to operate the company in anyway they want. Apple's a 40 year old business and everyone knows their culture. Employees know what they're signing up for (and I think their first day is an orientation about this topic specifically).
