The article does a good job calling out the more serious offenses, although I’d personally argue that nigiribashi is just as bad as the other two. Most Japanese people would probably react with a bit of shock to those.

That said, chopstick etiquette is definitely evolving. Something like chobujubashi isn’t enforced as strictly anymore, especially with more awareness around left-handed users. Kaeshibashi, on the other hand, is becoming more common, and in some social circles, not doing it can actually come across as rude.
