I believe the age thing is more about them not having an accrued history of personally-attributed content on the internet and how that weighed into making this decision.
Whether or not that's related to their age is debatable, but one would assume that people who have been publishing on the web for awhile -- bylined or anonymously -- would understand the negative impact this would have on their community or at least would have learned from previous companies' mistakes that just isn't something you do (both the deploying a global change that opts users into something they didn't initially sign up for and the very concept of making previously private things public). There are separate services out there that one can use if they want others on the web to know where they are and what they're doing. I'll use those if I want to be transparent.
