To promote business? No.
It is a directory. A huge group of volunteers, literally from around the world, who freely give their time to catalog lists of web sites that they think are worth being seen by others. There are editors on every continent.
The biggest complaint(s) about dmoz invariably revolve around "Why wouldn't you list my site?" or "When will you list my site?"
It is a bunch of volunteers working under no expectations to list
x sites but to list quality sites they choose to list with a description that will be of use to the web surfer......not to the advertising/marketing people.
A good read will be the official blog (updated just this morning)

Quote:...the future of DMOZ is as an information provider rather than a destination site.
I thank you for the opportunity to stand on my soap box for a few minutes and now return you to your regularly scheduled programming.
