Most of these are either born out of litigation from some nitwit who spills a cup of coffee in a lap and believes a great injustice has been done because McDonalds hadn't warned her that Coffee was HOT!, or through some advocate in Congress that believes that the public is too stupid to think for themselves, thus requiring disclosure for every little thing.
And _you_ are calling people "nitwits"? If I make a cup of coffee at home and spill it, I will say "ouch that's hot". This woman got coffee from McDonald's that caused third degree burns.
McDonald's offered free refills for coffee. So if a customer ordered coffee, drank it, got another one, drank it, got another one, that would cut into profits. McDonald's solved that little problem by serving coffee that would be far too hot for human consumption for fifteen minutes, so people wouldn't ask for free refills. Before this case, McDonald's had already settled for unknown amounts in seven hundred cases, so there was clearly a pattern of McDonald's intentionally putting the health of customers at risk for profit.
Of course a label "Warning: Coffee is hot" doesn't solve that problem, and doesn't absolve a company from every responsibility. That particular problem is solved by serving coffee at a normal temperature. You couldn't run electricity in uninsulated wires, put up a warning, and get away with it.
In other words, McDonald's didn't get done for not putting up warning signs. They did get done for intentionally, knowingly creating a health risk far beyond the normal accepted risk, in order to increase profits.
Unfortunately there are a lot of idiots out there, for instance Benadryl GEL/CREAM was recalled because they had a couple hundred cases of people EATING it so they had to add a new label to the top that says "DO NOT EAT".
People make mistakes. Good design steers people away from mistakes, bad design steers them towards mistakes. So how come Benadryl had to be recalled, and other products didn't? Could bad design be a factor?
Back to the subject of this thread: I don't want "clear privacy policies". I want my privacy to be respected. I also don't want mouth-foaming idiots complaining about perceived privacy violations that aren't privacy violations at all at all. And I'd want politicians to educate themselves first and not trying to get on some mission to score points.
