You'd be surprised at how much regular money some of the shittiest looking shareware made/makes people. And i guess that's the same case with the app store, there's a lot of crap that you and I will never need, but if we look for some niche thing, find it, pay for it, we have something we want and the author gets money...the system works! Sounds to me like the article writer needs to delete apps he doesn't like, pretty simple.
