A news story I saw mentioned that a Jewish owner of a non-kosher restaurant put up signs advocating for Israel. The article was generally positive toward the restaurateur for his Israel advocacy at a time that Israel is under missile attack.
Ignoring whether one may write the article in the first place, may one publicize it further (e.g. share the link)? Implicit in saying "Ploni put up an Israeli flag on his restaurant" is that said restaurant has no pretense of being kosher. Publicizing "Ploni owns a non-kosher restaurant" seemingly is prohibited because it is a violation of halakha (that one may not publicize a violation of halakha: Chofetz Chaim Lesson A Day, Day 1; that selling non-kosher food is prohibited: Yoreh Deah 117) I do not think that anyone will believe this restaurant to be kosher. While the name doesn't make it obvious (it isn't Ploni's Crab Shack or the like), I am certain that anyone going there would not eat there if they wanted kosher food.
