It's important to realize that copyleft licenses have as their goal 
ensuring freedoms (to use, modify, and redistribute) as far as is 
possible. Thus, restrictions on the ability to restrict the freedoms of 
others are generally acceptable.

A restriction that has as it's only goal preserving a privileged party's 
revenue or business model doesn't meet this criteria.
