You've got a good point, but do you really think an ethics class is going to stop Microsoft or Google? Do you really think an ethics class will make Facebook respect privacy?

I totally support the idea that all professionals need to be ethical and moral, and I definitely try to do so in my life, but I've given up hope that society at large is interested in this. I think individuals generally are, but any company, once it becomes powerful, seems to also become evil.
