I am not going to comment on the propriety of conducting these activities. However, it appears they had access to electronic communications that were publicly available/accessible. This is akin to viewing someone's non-private Facebook profile and/or Twitter account. By the headline of this article, I had access to their communications too!

Legalities aside, I would be concerned about how that information is used/what is done with it.
