Like I mentioned, there are perfect legitimate reasons and need to do it.
However, the best privacy practice is to never share it. If you share, then it is no longer privacy first. The goals which one wants to achieve come first. I'm not saying it will not have adequate privacy protection. But it's not "privacy first" because it introduces the risk to someone's privacy for the benefit of something. That something comes first.
