Well, I have submitted my survey.
I'm afraid I'm not at all hopeful though - in my experience, when a company (or government) has taken a decision they know will be unpopular, they run a consultation very much like this. So they send out surveys, and invite as many responses as possible. They then filter those responses, finding as many creative ways as they can to disregard responses that don't agree with what they've decided.
And then report the 'results': "We've been delighted by the response. We had X thousands of responses, and the feedback was broadly in agreement with our plans. We will make some further adjustments on specific points that were raised, and will publish our new and final version soon. Our sincere thanks to all those who responded."
Basically, the word 'consultation' has only three letters.
