Everyone wants high quality search results, of course. But like I said in my OP, Google is a for profit company that depends on high traffic keyword searches and high volume publishers to maintain their livelihood. It's not that far of a stretch for them to not necessarily be dying for "quality" search results as much as we are. If the lower quality results are making them money, it would be against their own business model to squelch them.

So it really is a question of who this issue is affecting. For us, it's annoying. For Google, it's a profit source.
