I doubt they'll find out and even if they do I doubt they'll go to the effort and expense given the how few people will likely use a site like this vs the numbers of people traveling through an airport. Even if they all do add some other security then it's just like going back to a time before this site so no great loss. The alternative is to not share the passwords on this site which is effectively the same to anyone trying to get on the wifi for free.
