So why would these other women want to "expose" the relationship? They knew he was married to start, why would they want to make it public now? What is in it for them?
I would venture to say that not one of the women Tiger has seen, did not think about the money in the future. All of these devious bitches have made money and 10 minutes of fame. Money was in their mind as soon as they laid eyes on him. This certainly doesn't make what Tiger did right! Staying single would have been a lot less expensive.
