I think the point here is that the people performing the actual experiments think that the amount of animal testing is inappropriate. If you do an experiment and it ends up killing the animal, that is one result. One data point. If you do the experiment 100 times and it kills 100 animals, that may be a signal that you need to work out some theory and not a signal that you need to go ahead and kill another 100 animals. If this were just PETA or something, it would be pretty easy to ignore, but when the employees performing the experiments are complaining, I think it's pretty reasonable to pay attention. These are people that signed up to work for the company. They knew that animal testing would be involved. Many of them had probably already worked on experiments that utilized animal test subjects. And these are the people saying that the level of animal testing is not appropriate.
