Ethical dairy is yuppie BS meant to make us feel better about participating in an inherently cruel system. This is still the same system that leads to the death of every animal involved (males for veal as babies, females after 4-5 years for meat when they can no longer produce milk). 

"Traceable Milk" may be a step up from factory farm milk, but it's certainly not worth a huge amount of praise.   If this ice cream creator was truly concerned with the ethics of ice cream, she would be developing one with coconut or cashew milk.
