I would agree. I do think that corporations should not be treated in precisely the same way that individual persons are treated. Corporations have (arguably) far too much power as is.
But I think that the level of privacy that allows one to request to not be videotaped against their will extends to corporations in some circumstances. Unless there is something truly fishy happening here, and there is not much evidence that there is, I believe that Google is within their liberties to be upset over this.
