Google is an organization run by engineers. They have no concept of marketing, or product placement or community engagement. They build for an audience of engineers, and if a wider cross-section of the population embraces a product that is purely by happenstance rather than design. As an enterprise they appear to have AD/HD, these products are launched and supported for awhile and then dropped. It is baked into the corporate culture, and I don't think it will or can change.
