I suspect that this comes from tunnel vision and not interacting with enough casual users. Hypothetically, if the feedback they're seeing is that people desperately want jobs and will do whatever it takes, they may only be exposed to a subset that would have no qualms with making the info public. Especially if that subset is already out of work.

I can imagine, in that scenario, not thinking about all the devs who signed up over the years and are no longer searching, or are searching but doing so quietly.
