Considering people link their personal social media accounts to xda. I don't think 99% of people really care anymore.Privacy becomes an issue. Most people don't follow best practices for their online identities, and are easier to track and hack and whatnot. It would be good to mitigate it in whatever small way possible, no? Even if they use their real names elsewhere, XDA becomes one less attack vector.
Gone are the days of personal privacy for most. Don't get me wrong. I don't agree with this shift but I see it happening.
A perfect example is, the other day I was talking to my bosses daughter. (mid 20's) and it came up about all the traffic cameras being placed all over town and how it invades the privacy of everyday people. She responded with out missing a beat. "you know it has always been that way for me so I never really cared"
Many people have forgotten the dangers of the internet and giving your info away freely.
