I think people who want to just say "you knew what you were in for" are reveling in the schadenfreude rather than being realistic.
The layout of Marvel was not known or advertised when tickets were first released, and a lot of the 'premium' seats were snapped up at that point.
It's also not impossible to come up with a seating configuration that would have sacrificed numbers in order to provide a better view for those on the ground. Even a slight incline would have helped enormously, and the ground could have been tiered to create that. That would have sacrificed some of the fixed seating, but it would have made the 'premium' seats a lot more premium.
My objection is that if you go to the theatre, a concert, and even some major sporting events, you can buy obstructed view tickets. Often those aren't released until everything else is sold, but they're designated as obstructed view and you know what you're getting. Selling premium seats in the full knowledge that you won't be providing a view of the game is poor form.
IMO, I don't care about a refund. If I couldn't afford the money I wouldn't have spent it, and it was a worthwhile experience, even if the overall execution was underwhelming. My concern is that I wouldn't bother doing it again, regardless of who was playing. If I feel that way, and a lot of others feel that way, and the media coverage has been overwhelmingly negative despite what should have been a good outcome, what happens when BA attempts to do this again in the future? How many of the 50,000 attendees will be back? Is attendance next time going to be 30,000? 20,000? It should have been a showcase and celebration of Australian basketball for fans and media, even if that meant fewer $$ earned. Take a long-term view and grow the game instead of just scrambling for every cent you can get right now.
