What's the ethical situation for a journalist who leaks this like? How long and hard do you question the agenda of your source? Don't you usually need multiple sources before you publish something like this?
I'm not a journalist but am curious how these "insider info that most certainly will influence the deal price" scenarios are generally handled.
It is often the case a leak is intentional. The Journalist gets their story - leaker get the intended word out with Anonymous Source protection (the "greater" ethic). In this case the motive may be lead time for other bidders to throw their hat in the ring.
