Some knew. Apparently Samourai said that "only" 30% used the honeypot default dojo. That degraded massively the privacy of all that ran their own dojos and ... well @Bitcoin Mechanic really said all there is to say in the video. Him, myself and many others warned about the xpub issue and sure enough, Scamourai kept all the logs for the feds. So conveniently. And now they went to jail for 5 years, will probably come out early or something and the rest of us will have to live with this precedence.
