Thankfully, people tend to interpret legal terms the way the law does, not the way you do -- this is a good thing, as you obviously have no clue as to what the hell you're talking about. Here's how the 8th edition of Black's Law Dictionary defines extortion (quotes removed for the sake of my tired, tired hands):
extortion, n. 1. The offense committed by a public official who illegally obtains property under the color of office; esp., an official's collection of an unlawful fee. 2. The act or practice of obtaining something or compelling some action by illegal means, as by force or coercion.
There is absolutely no chance the RIAA is making any money with all the legal fees they are spending here. Typically they ask people to settle for very small amounts. Lawyers cost hundreds of thousands or even millions just to hire a few.
Got any numbers you can cite? Any references at all to back up your supposed knowledge of the RIAA's legal expenses and profits? Or are you just making stuff up? Put up or shut up.
