Last weekend we flew LHR-GIG in Club World. When I booked the flights in late November, of the 35 CW seats on this 787 Dreamliner, all 10 window seats were already taken. Even when check-in opened at T-24, no additional seats became available.
At the time of booking, you knew all the window seats on this flight were taken. If being in a window seat was so important to you, you should have booked on a different flight, just as someone who wants to travel in F should avoid booking themselves on a flight where all F seats have been sold. You certainly don't have any right to dictate to those in window seats whether or not they are allowed to have the blinds closed.
