Because cyanide stuns the fish and you can literally just pick them up off whatever coral they landed on. It also tends to make their colors abnormally bright, therefore they are "prettier" specimens worth more money. And yes, probably hundreds of collectors used it at one point. Now there are not nearly as many, but there are some people who use it, especially in the Philippines.
P.S.
It is very difficult to discover whether a fish was collected with cyanide. They might not eat at all, or eat ravenously and die anyways. When you look at how dangerous a chemical cyanide is it's not really surprising what strange effects it has on fish.
