Earlier quoted context omitted.
Do they really? Wouldn't a "strong SEO" site be ideal for their spiders?
I guess sites with real, useful content (e.g. Wikipedia) don't need strong SEO since they have a ton of back-links from other sites that validate their high ranking, so "strong SEO" is really about making a less useful site look more useful, which makes sense for them to hate. SEO really translates to "How to fool Google into boosting your ranking artifically".
So much so that I now specifically use their search tool rather than go through google just in case some interesting thing pops up.
