here’s another good reason to vote ‘yes’ for 7:
no more than 40% of the board may be representatives of a single company. of course, due to the fact that board members come in integer quantities, it’s rarely possible to hit 40% exactly. under the current board size of 11 this means that, at most, 4 people from one company can be on the board (4/11 = 36.4%, 5/11 = 45.5%).
in the pathological case this means that the board can be entirely filled by 3 companies.
with a 7-member board, the greatest possible number of people from a single company has been halved to 2 (2/7 = 28.6%, 3/7 = 42.9%). this means that even with fewer positions, 3 companies could never hold all of the positions on the board. it also means that any single company has less than 1/3 of the seats (whereas before they could have more).
