I misread your comment the first time through, but the misreading gave me a profound idea... "Why doesn't Google black-list the names of the copyrighted works?"
Yes, of course. But it's mostly a rhetorical question. You see, the new auto-complete filters are banning the terms of legitimate services (albeit theses services can be misused) in conjunction with terms of copyrighted works (e.g. <photoshop rapidshare> or <rapidshare photoshop>).
It's the combination of terms, so if one should be banned to please copyright holders, it almost makes sense to ban the terms of copyrighted works. After all, it's the copyright holders pushing for this kind of filtering.
Food for thought.
