I have made a note of this singular action along with your repeated refusal in this thread to acknowledge the harm you are causing.
People don't want their current employer to know about their job searches, period. There's a difference in magnitude between this and the Ashley Madison leak, but it's the same concept. Having a profile at all is a clear sign to your current employer. It doesn't matter what you were doing with it or when you created the account.
I wonder, what future value will you find by giving away more private information? I know by this example that you won't even wait for the consent of your users before you exploit their private information.
The existence of the job search itself is the issue. I'm not sure what's not getting through about that.
Now if this blows up there is an even bigger target on Ammon's back and he may be panicking. That or he is a scumbag. Could be both.
It’s like explaining to your spouse of 5 years why you have a profile on a dating site that started 3 years ago.
Is that OK with you?
You are totally missing the point. You think the change significantly improves your product, but your users perceive the change as a massive breach of trust. Why? Because the underlying JTBD (job-to-be-done) for a lot of engineers is discreet job searching. IOW, for a lot of people, a public TB profile would be like having a private Ashley Madison profile [0] exposed to the public. Ashley Madison was a major source of embarrassment for many when they suffered a breach.
Rather than double-down, might be time to step back a bit. The aphorism "the market's perception is your reality" is especially instructive.
[0] The Ashley Madison metaphor used by this commenter is especially apt: https://news.ycombinator.com/item?id=23280782
