I do not think there is any prohibition on use of any particular financial products. Even there will, it takes time for laws to come out and to be passed. The markets are not good for them at this moments, but they probably will bounce back just like previous financial crisis.
Those complex products are not really so complex if you understand what their purpose is, in the same as a medicine treats certain disease.
You are right, media, who usually are not capable of understanding these special products, like to generate publicity.
When you say, 对 赌, I guess you mean " hedge" ( =对 冲" ) Hedge here in its English means to reduce risks,
Hedge fund = 对 冲 基金.
