Usually when someone breaks out an analogy like this it's because the comparison is not like for like and there is something they want to obfuscate. Quite simply, because Steam is not Google. Steam's value is in all the games you want to play being on Steam, not in its discovery algorithm. It loses nothing by exposing that algorithm because even if you had it, you would not be able to build Steam as you do not have the games that are on Steam. It has vendor lock in. There's no such lock in for Google. Google doesn't have exclusive rights to the websites it indexes and anyone could, it they had an algorithm as good as Google's (and the computing resources) build Google. The only tech factor holding Google in place as the #1 search engine is that its algorithm is better than everyone else's. The algorithm is intellectual property that Google has invested billions of dollars in developing. Providing the weightings (and allowing as some people are suggesting the ability to hobble Google's algorithm by using your own) would be the first step towards someone reverse engineering Google and be a material business risk for them.
