So I heard this hundred times before and while it feels like Google (in this example) is making mistake, perhaps the second bottom here is that they wanted to shut down a competitor (at some field) and the nice way of doing it is to acquire. Then Google won't care if they find themselves behind gold cage of Google or not. They may leave or whatever. I don't think dropping $30MM is a big problem for Google either. For me or you that may be a waste, for Google it is 1) drop in the ocean 2) cheap way to shut them down.
