The funny thing is, it's only on circles like these at HN that it seems the corporation should "take the criticism."
As far as investors/Wall Street/the wider public goes, the non-answer might actually be the better response. Appearing to take the criticism seriously could be more damaging--hopefully internally, they are indeed taking the criticism seriously.
We all know this because we, in theory, all want to operate ethical companies, and companies that stand for what they are, not how they seem. We endeavor to seem as we are. Perhaps blackberry could once again lead the pack if instead of improving their image, they improved their company and let the image follow.
