Uhh... Yeah? Everyone in search does this. I've worked at and with 3 major search engine initiatives, and we all tested heavily against Google in a variety of ways.
But the article definitely gets a few things wrong. For example, having worked at Bing I can tell you this: in general "obvious" misspellings are autocorrected without comment. It's not some sort of magical copying procedure, it's actually a policy. Want proof? Here's an example query you can repeat: http://fayr.am/4KdG (direct query link: http://fayr.am/4JZD)
But otherwise, shit yes everyone is scrutinizing google trying to figure out what they're doing. That doesn't mean other players aren't doing their own optimizations, or even running relevancy metrics against other search engines. Relevancy is not a concept with fixed metrics, and every player in the search market does everything they can to figure out what their competitor is doing.
And even the raw results leakage is fairly par for the course. It's not like Bing searches are a crawl of google searches; Microsoft gets this data from browsers running this toolbar and uses it to help shore up queries where they don't return good results.
