Reminds me of a semla(a Swedish pastry, and a big deal) competition Arla(cow rapists) had here in Sweden a couple of years ago.

The rules where you could use products of any brand and not just Arla, and the winner would be decided by popular vote. Rather quickly a vegan pastry shop got first place by a really high margin to second place. And just like that they got disqualified because the rules changed so now you had to use Arlas products..
