I noticed Rav Abadi says all soft cheeses made by gentiles are kosher.
Do other poskim also hold like him? If yes please post who.
Both cottage cheese and mozzarella require rennet, so I'm not sure why companies like OU make a difference. Why do soft cheeses made by gentiles, like cottage cheese, have a hechsher, while others like mozzarella not have a hechsher?
