I think some of what Matt Cutts is saying is simply trying to scare people. I think they will start to remove some really really low quality sites especially autoblogs and content scrapers, since they should be relatively easy to detect. However as the OP shows, detecting content farms and other low-quality sites is quite a subjective matter.
I say this because loads of the bloggers seem to be complaining about sites with small amounts of content, in some cases just a few pages of content in total. So Google could mean that they are going after large sites with thousands of pages of low-quality content, however they could just as easily mean the really small sites with only a few pages of low-quality content.
As someone who puts out quality content, I'm not exactly worried about this blog post however it will be interesting to see what Google does consider content farms to be. The cynic in me unfortunately can't help but think that they will go after the small guys but leave the really large spammy sites such as biz rate and wise geek alone.
