One: He was not at a cabaret club, or other possibly exploitative business.
Two: He was socializing with private acquaintances with his private life and not doing anything illegal (drugs), disrespectful (rude hand gestures, violent acts), or even against the Johnny's "image" (kissing).
Three: The photo wasn't something he carelessly posed for and then had get leaked, it was clearly taken without his knowledge.
So all in all, in my personal opinion, Inoo did not do anything wrong here, and it was a clear invasion of his privacy.
I'm glad people have mostly calmed down about it, but just to be clear, it wasn't a cabaret club, and he wasn't doing anything inherently disrespectful, so I hope this helps clear up some confusion.
