(I'm not too sure where to put this, if it's int he wrong place please move it)

I was just looking at the VOZ website which is realeasin version 1.1 tomorrow. I decided to look at their file hosting application and notcied this stipulation:

2. You must not be an agent, employee, business partner, affiliate or have any business dealings with avsim.com, flightsim.com or simviation.com

Does this mean they don't want the 3 largest add-on sites hosting it? And if it does why??
