Fact is, the rules don't even say how the prizes would be awarded, let alone how many. It doesn't say anywhere that winners will be able to choose from the "pool", with first place getting first choice, etc. One could assume that all the winners get ALL those pieces of software from the way the rules are written. There are very strict legalities surrounding contests. One of the strictest is that the rules MUST clearly state what the prizes are (and their value, BTW) and how said prizes will be awarded. And you can't change the rules after the fact.
