Because you are so pro organics.
Seriously, I agree with you about the people this article reports on. However these issue are not negated or alleviated by growing organic. These people are just being schmucks and using stupid growing techniques that were outlawed for a reason. Now personally, I don't do organics for a few reasons but it boils down to that with hydro I have far greater control of the nutrients my plants use than any soil based method. If I have a BIG problem in hydro that is nutrient based it takes no more than 7 days from diagnosis to recovery. (Inert medium. Hydroton) If I can read my plants correctly I can tailor the entire nutrient solution to the plant. I understand plant biology and know that when the plant finally uses the chemicals they are far different than what goes in the soil. And that much like any living organism the plant will not use what it does not need. Now, these are of course simplified terms, but you get my drift.
I do not disagree that you can get great results using organics. But for me, hydro is the best. Diffrent strokes and all that.
Although I disagree that you can push the nutes a lot harder. If you push too hard with organics you have to flush and flush and flush and change your nutes and teas and all that. If I push too hard I drain, fill, flush, drain fill, done. And recovery is usually 4 days or so.
Some people prefer to grow organically, in tune with mother nature. Others prefer to grow in a lab, in tune with the universe.
