Knowledge article rating’s transparency in the new HTML5 self-service portal

Exploring the HTML5 System Center 2012 R2 Service Manager Self-Service Portal updated in January 2016 I’ve noticed one curious thing about the knowledge article’s ratings.

If you look at the source code of the portal page of any knowledge article that has ratings set by end users, you can see all rates and comments. I don’t know if it’s god or bad and why Microsoft developers did so. What do you think?
