Then I would suggest that if they're that sensitive to questions from their customers, they are in the wrong position. Responding to your customers feedback should be one of the top priority jobs of a CM.
You are right, the answer was given yet people think they have been invited to discussion. I personally feel that people answering the questions in forums are not authorized or not qualified to participate in these discussions. Suggestions and questions are mostly based on hypothetical conditions, while anything posted can and will be used against them.
Just to add one more thing, responding to customer feedback is also very vague. In most cases an answer to a feedback is "thank you for your input." If you were in this position you would realize that you can not agree nor disagree with customer opinion. You just accept it and provide response based on current company policy. There is no discussion involved at all.
This means that asking a question, receiving a response then asking a 'what if' follow up question, is not likely to get a response.
