Why the concern about Google?

Why the concern about Google? Criticism of Google’s tax avoidance practices continues to rumble on in the newspapers. It is, the critics argue, a case of Google not being “good citizens”.  This is to miss the point completely. If Google’s (or anyone else’s) actions are immoral but legal, then surely it is the law that needs to be changed? Law and morality need to be congruent. That surely is the issue? Or is it? It may be that Google’s profits are a rental stream derived from the conceptual enclosure of some kind of public commons in cyberspace. I do not know the answer. I only pose the question.
