I see so many posts about how people hate the market wards and how they want an AH instead. I'm not sure if this has been answered or not yet.

What is the reason for SE standing behind the market wards system so sternly?

Is the reason why they seem to be against an AH because they want the markets to succeed and be recognized as something new and innovative?

The idea of both systems are fine to me. I don't know if SE has given an official response to their point of view on this subject but if they haven't can we get the answers to these question please?
