How would that be better? If they aren't listening, that would be a lie.
And from the open letter saying "RIM has a culture where nobody can speak out without fear of career limiting punishment" their reply is "I can't believe any real employee wouldn't raise these issues internally", does that sound like they even thought about the letter for five minutes?
A better (more honest) reply would be "we don't think there's a problem, Apple is just luck and hype, the playbook is industry changing (Mike said that, didn't he?), this better not have come from inside or else".
IMO.
