I have a feeling that MS is playing with fire again.... That every request made through the edge browser for a non local user is associated to his/her live ID is pure coincidence ;) Sometimes when I look into my dns logs, I cry a little bit inside too.
That's the moment you fire up Firefox without prefetch nor studies and enjoy the peaceful DNS logs without the constant telemetry calls to LinkedIn and to all interested 3rd parties, five eyes etc
but firefox has different dns requests going to their servers as well.
