Google Doesn't Buy Olive After All

Remember the rumour about Google buying Olive Software? It seems they decided not to buy this company after all. But the story is extremely interesting:

Google sent out a team of 15 people to Olive's Israeli offices (much of the company is over there) for over a week (staying at an expensive hotel), and interviewed each Olive person several times both in person and by phone interviews.

It all seemed like a 'go,' but then the Google team suddenly decided the product didn't have everything they wanted.

Did Google just want to know more about Olive Software's technology? Or maybe they just wanted to hire some of the team members to create a similar product?
