The main issue is that often a farm isn't merely some small farmers property. It's the place where big agra policies are being enacted.
Few people would be outraged if someone smuggled a camera into a big factory to document abuses. Be skeptical of privacy arguments here. This is the equivalent of a big manufacturer contracting out to small sweatshops.
I also know the guy who owns the dairy the film was taken on, and I know quite a few of the people performing the most ageegious acts were fired soon after it was published.
But, as an issue, the film was just published, in the most sensational way they could, and NO effort was made to contact the dairyman ahead of time. The point of making the film was not help, but to hurt, permanently.
The film that was produced, is being used against all areas of the milk industry. The people using it add words to the effect of "this is how all dairies treat their cows". I've already seen it used in campaigns against yogurt and cheese producers.
Also, the debate continues over here about the law. Some dairymen are campaigning to reverse the law and open things up completely. But a big issue is education, too many people in America have never really touched a cow, and think people treat them like a cat.
I also don't understand why the publisher should have contacted the dairyman beforehand. What purpose would that serve if the video would eventually be published anyway?
People care about where their food comes from now a days, and you're right that the public is ignorant of dairy techniques. However, you can't complain about the public's ignorance of dairy farming while at the same time decrying a publisher for making a move about dairy techniques. Censorship is not an effective means of education. If the dairymen want the public to be better educated then they should open their farms up, or start making their own movies detailing how they raise cows.
