Exactly. I've had the idea of using Google to find information ingrained in me since elementary school when they taught us how to efficiently search with it. I use Chrome, google apps for business, google talk, android os, and plenty of other wonderful Google products simply because they are high quality products supported by a name I can trust.
I haven't thought much about Google in decline as I see it as almost impossible at this point in time. They have the number one search engine in the world that is used by a crazy 1/6 of the population on Earth. With other tech giants though such as Facebook, I've been thinking recently about whether or not they're declining already or if they'll continue to grow.
I think these cases is about making a statement rather than improving anything for consumers. The attitude of consumers is pretty clear given that most everyone uses Google. If I felt like I was being deprived of good search results I would switch.
How many people here on HN have wondered if Google is in decline anyway? I know it's occurred to me. What is the government hoping to do with this case?
