Well, but the essential difference is that the maximum payment is for 25 posts, instead of the 50 that CM used to pay. It's double the pay. That's why I was wondering if some ex-CMs might be tempted to build up an alt to get paid for 50 posts.
With the case you mention, things have actually changed, and there is no longer a deflation or reduction in pay due to supply and demand. The whirlwind.money campaign has hired many of the best posters, giving them the maximum pay per post, in turn these have left vacancies in other campaigns that have had to be filled, so I think it has been a blessing for posters who post constructively on the forum.
Hopefully more campaigns will come along and push the rates up.
