You don't see any difference between the maintainers of PHP telling the whole world, "try to find a bug in PHP in 24h", and one random guy on the internet telling another random guy on the internet to try to find a bug in Nginx, Apache or IIS? Surely making all interested security researchers with time on their hands focus on one thing with a specific deadline has no effect on the probability of finding a bug in that thing?
