That said, I strongly disagree, to the point of revulsion, with the implicit desire of the author, which I see echoed in various forms and about various subjects, that the government take action to ban any of this. ("Imagine if 65% of the population had a gambling problem and we let the banks put pokies inside ATMs." - emphasis mine).
It appalls me that HN is so adamantly desirous of the freedom of the press, the freedom of anonymity, the freedom of assembly, etc., but sees no problem with calling for the mass restrictions of freedoms in work, housing, healthcare, and the like. Even, apparently, the freedom to choose what you eat. It's revolting to us that someone might decide what you should be able to say, but we are happy to make moral pronouncements from our padded office chairs on others' behalf, as long as it's something that won't affect us.
Let me be clear - I am not absolving these companies of all wrong. They commit fraud when they lie about ingredients, they are implicit in assault or even murder when they sell actively toxic (as opposed to simply unhealthy) food and advertise that it is safe, and they regularly abuse our screwed-up political system to gain unfair and immoral advantages over competitors. These things are all wrong.
Selling unhealthy food, with an honest description of what's in it, isn't.
He even mentions it in the post - consumers are voting with their feet. We can disdain the stereotypical "people of Walmart" all we want, but we have no business forcing them to live the way we think is best. We're no better than the NSA if we start going down that road. No one is coercing them to buy there. There are plenty of cheap and healthy alternatives. We just have to come to terms with the fact that they are making a poor choice, and we have no right to force them to stop.
We absolutely should encourage them not to. It's perfectly fine if you choose to boycott these places. It's fine if you don't let your children eat that food, and it's fine if you make it your life's work to making that food obsolete. But you have to draw the line there. Once you start forcing people, at the threat (ultimately) of death, to eat certain things, you are no better than the NSA forcing people at the threat of death to say or not say certain things. That's not our place.

All that said, he's right. The world is, as he bluntly puts it, "fucking insane", and this is one of the ways that shows.
EDIT:
Holy cow, this article got flagged to death. Probably rightly so. It's on the third page right now, despite having 65 points in 2 hours.
