Aloha,
As I do understand your concern, as a retired Sailor and someone that taught operational security and security with personally identifiable information, I can tell you, no data is being taken from these surveys that could be used to hurt anyone, nor is any data being sold.
Furthermore, the survey is optional. As was stated last year when we started utilizing ID.me as a way for us to identify veterans and active duty personnel that play the game (this too is a safe site that gathers that voluntary information and shares it with partners) none of this information is gathered with a negative connotation in mind.
Mahalo,
