As a Google _user_ I care a lot about this issue. A lot of the technical topics and questions I search for are answered best by blog posts from people who've solved the same issue, or are an authority. I don't want them thrown out with the spam, and I don't want all such content to have to be hosted on sites like Stack Overflow to be findable.

Yes, now we are in agreement. For the users of google it matters, but those are not the people that are currently screaming blue murder, it is the webmasters who had a ton of traffic from google before and that lost it (fairly or unfairly is a case-by-case thing).

If users no longer find relevant content then that is a real problem but I think that in this particular respect your goals and google's goals are very much in alignment. In other words, if they could do better they would.
