To be fair, unlike other corporates, Google is more used to being loved and spoken in high esteem than being criticized for their actions as an ENTITY. I would say that they need more criticisms to improve themselves as an entity and in their actions.
I also don't see anything wrong in understanding the real intentions behind their changes. Sometimes we may be right and sometimes we may be wrong, but I wouldn't agree that understanding the underlying driver or objective isn't going to help.It would definitely help in laying down our assumptions and we always have to work with some positive and negative assumptions.
Corporations in any field are a human challenge whenever they hit a certain scale. New effects appear that can look like "evil".
In most corporations, the workforce is just an implementation tool and the vision or underlying objective is determined or laid down by a small group of people. For example, Amit has the dream of making google an answer machine that can answer any question. He wants to make his so called childhood dreams about star trek become a reality in some form. He doesn't care that in attempting this, Google might sound more monopolistic (dictator?), thereby forcing several third parties to oblige them, though they really don't want to. The small group of people, who have the real power, is in agreement with his dreams and believe that it would be beneficial to the corporate as well.The rest of the workforce is just a tool to help them realize this dream or high level objective. So blaming the bad effects (for the users or the webmasters) on the workforce would sound more like an attempt to pass the bick.
