You haven't made an argument, you've just used longer words to restate your (incorrect) opinion.
Also I never said they had an 'advisory' board. Board members ar either executive or non-executive members. If they're nonexec then their role is to advise the executive members. They're generally fairly independent and many nonexecutive board members serve on the boards of multiple companies, sometimes including ones that are nominally in competition with each other.
