Is Google a fool in Baidu's eyes?

Any Chinese person knows that "sb" is a colloquial abbreviation or nickname for "shabi," which means "idiot." However, according to the Baidu search engine, Google's second-level domain **http://sb.google.com/** ranks first among all search results for the keyword "sb." After some investigation, it turns out that Google’s "SB" stands for "SafeBrowsing." What I don't understand is why Google didn’t use **http://safe.google.com/** to denote this safe browsing feature, but instead chose **http://sb.google.com/**, which might seem quite "sb" (stupid) from a Chinese perspective. And Baidu seems happy to place this joke about Google at the top of its search results.
