GP was not simply describing - they were excusing. "Oh well, some corporations are evil, don't complain, it's not their job to be good corporate citizens."
Actually by calling out and disagreeing with this behavior we can change it. The most effective way is through strong regulations, but the current US government system is broken and flawed. But at the very least we can use websites such as change.org and sumofus.org to put pressure on bad corporate actors. Hell, we quite often see the same thing happen on HN in miniature when someone makes a post calling out a company - and that company is forced to respond to the resulting negative publicity.
"The only thing necessary for the triumph of evil is that good people do nothing", and all that.
