Look at some of the arguments put forward by the anti-aquarium crowd, and you'll know the article is basically true. See also Julian Sprungs discussion on this at, I believe, the 2014 MACNA. (it was in another thread). Or browse through all the other arguments for/con the Hawaii ban. Also note the fact that they've been at this for a long time, always trying legislation and lawsuits to force this - best is example is the complete ban on coral keeping in Hawaii.
Basically, there are a good number of people who want to ban aquarium and collection for various reasons. Their science and data is always poor; the argument is always in the end an emotional one.
