I find it ridiculous because they are blaming an epidemic (somewhat caused by their own actions) on an individual's ignorance of computers (likely). She is not being sued for downloading music, she is being sued for sharing (to which she probably was ignorant to).  The 54k in damages (or 2M?  who knows) that they want to collect is not because some mother accidentally (or not) shared some files. Also, it can be said that they are not protecting their IP very well if she and one other person is being sued out of the likely 50 million or more people that are downloading music illegally (or have at some point).
