I didn't, I think its true. I'm shocked google actually did this, it will cost them money in advertising dollars, and I honestly thought some of their technical decisions were being driven by maximizing revenue at almost any cost, so this move seems to invalidate that theory. Kudos to google I say.
I completely agree. They must improve (or at least) maintain the quality of their search results to keep users. The fact that it is the most popular search engine is what brings in advertising dollars in the first place. So, the users are the key. SEO spam hurts them, just like it annoys us, so this is one of the attempts to fight it.
