So blackrock/vanguard can "hide" their "big" investors, depending on the company "invested in", or is this public info? That said, it is actually blackrock/vanguard ppl on the boards, and often they are the biggest ones, and expecting no steering from them or the "big" investors behind would be... "unexpected". Their is also the massive debts with the gigantic interests to be paid all along the calendar year. In the case of starbucks, owners of the debts is public info or the web page is incomplete? That said, now I understand why online non-franchised/licensed starbucks stuff has the aspx file extension.
