If I was to give some slack to the teachers involved, I could say that the unfamiliarity of their new surroundings (in China) may have caused their hyper-defensive and critical and attacking attitude. Also, many teachers in China have chosen 'teaching' as their second career (previously being employed in some non-teaching role), so there is a certain amount of inexperience that teachers unwittingly (and unfairly) convert into hostility, defensiveness and criticism; when unsure, go on the attack! This is a personal issue for each individual and WEB International (nor any employer) can not be responsible for the personal state of mind of its employees.

The best teachers (in my experience) are those who are happy and patient individuals, and ready to 'give' - after all, teaching is a 'giving' profession!
