It saves time. The most you can actually get from such an announcement is to slightly update your priors. It doesn't affect your actions at all. So you see it, note it, become slightly miffed that the Internet will be full of comments that think it's a bigger deal than it is, and move on with your life.

The cynicism serves as a mental balance to the hype that might otherwise tempt you to spend more time on this than it merits.
