Honestly, I've written some pretty controversial things on HN, but your response is frightening.
Bad behavior, behavior that some people would say is more than little evil, isn't excused because other corporations behave just as badly.
The fact is that the behavior we're discussing is quite easy to get right: just stop forcing people out of their jobs when they're sick or pregnant.
Your response is like saying "human rights violations are such a big problem that we shouldn't do anything about it".
It's a good thing that there are people that say we should stand up against hyper-wealthy corporations who are actively trying to exploit and harm their employees, instead of making excuses and looking the other way.
