Interestingly this is in my opinion exactly the sort of attitude that is killing the asset store. By killing the goose laying the golden eggs the primary loser is the general indie developer who uses the asset store as a place to learn and get things done. The asset store is the reason I think that Unity has succeeded as well as it has in the indie community. The primary reasons that developers leave the asset store are twofold I think - its not financially viable - and trolls. I have dealt with a bunch of them and even today I read another one putting my assets down in a review they left on a competitors asset as they have done now on a bunch of my competitors assets because, for whatever reason this toxic individual has taken a dislike to me. I have talked publishers down from leaving the store a bunch of times and have seriously considered walking away myself and going back to the commercial world as its easier to make a living and I am paid well and treated with respect. Fortunately for me, and for the people who like my tools, I stay here because I love the work, and the positive aspects of the community generally far outweighs the bad. As @recon0303 said, the price here is nothing compared to commercial rates, and when developers get burned we all lose because their products get abandoned.
