Definitely a step in the right direct, are you listening FIOS?
Yes, getting commercial free episodes either through Torrenting, Newgroups, or web sites is great, but not everyone want to watch the episodes on their laptops or PMPs (I use my Zune for this), and far from everyone knows how to, or wants to stream from PC to TV.
Remember - the viewers of this site are, for the most part, far more sophisicated than the average Cable subscriber. This approach works well for them.
Of course, one can alwys DVR the missed shows and skip the commericals on the playback (or can they?).
