Ralph never added that qualifying statement until today that "doxing is fine unless it's a random" he's always said he didn't give a shit about doxing, it seems his position gained some nuance once doxing started affecting his bottom line. With regards to saying it isn't the same as Kitty getting doxed in actuality it is the same, the initial argument wasn't that Ralph was losing money but the potential for stream.me to lose money which in the case of the Kitty dox did happen, stream.me lost the money from his subs. So there's a bit of a conflict between, "it's ok if other streamers get doxed" to "it's NOT ok if paid subs get doxed" because both have the potential to affect stream.me and any associated streamer's bottom line.
It will be interesting to see the aftermath of all this, Ralph is lucky his alogs are complete brainlets. If we see some more anti-Ralph streamers set up shop to troll him then Ralph will have a boogieman to go against and retain some of his viewer base. If no one comes then the well will start to dry and Ralph will need some drama content to slate his viewers, or we'll witness the inevitable Zoom turning on Ralph arc and IBS Apocalypse 2.0 will begin.
