I think it's a little unfair to accuse Google of copying anything that works. Google moves too slowly these days, often I watch as they work on a product ages before someone else comes up with it, but they take so long to launch that they're passed up by startups, and by the time they launch it looks like they're a copy cat. Just to give you an example, Inbox precedes MailBox by years. I joined Google in 2009 and they were working its various incarnations even back then. Also, doing what other people do is not necessarily "copying". When Google entered the Search market, there were plenty of search engines. They didn't "copy" search, they make their own. When they introduced Chrome, there were plenty of browsers, but they put their own spin on it. It's not just about the ideas, but about their implementation and execution that matter.
