Maybe they were illegal. The point is they are companies and can do whatever they want, largely without scrutiny. I mean this in the sense that it is difficult to bring charges against them, as evidenced by basically the entire financial sector. When things like this are published it just serves to dissuade them from PUBLISHING the results of the experiments but not from actually CONDUCTING THEM. I would much rather know when they do things like this than have them continue to conduct them in secret.
