I believe what they did is took the one they wanted and put it up against the worst one that the artist produced.
The vote was "legitimate" but disingenuous. It was like voting for which to eat: a ham sandwich or a plate with a dog turd on it. You know which will win, you don't need a vote.
They hyped it up as though a bunch of the fan submissions would be voted on but in the end it was only a selection of two by one artist. Why not three or four selections to vote on? Well, because they can't as effectively control the outcome then.
The speed at which Melbourne City adopted a copy confirmed my suspicions that they planned this.
For the record - I prefered the shield, and voted for it. As I've said in a number of other places, I followed social media extensively for the badge vote, and up until about a day before the winner was picked, I thought the shield was edging the vote in terms of popular support.
Anyway, I'm also going to leave this debate because this is a road I don't really want to go down again.
