It looks so weird! Especially when you see it on an email search field of a private CRM system.
Of course I logically know that this is not an information security risk, but it feels sketchy. I am surprised it was shipped, and frankly also surprised it hasn't been rolled back. Someone else in the thread raised the point that this kind of UX can snowblind novice users against future phishing attempts.
I do appreciate that DDG is a company we can collectively engage with feedback like this in such a manner. I'm certainly not quitting them over this.
