I voted no because Im a evil money grabbing old git capitalist that doesnt want competition im my quest for ultimate world domination
All kidding aside, I am sure there would be a strong demand for an FOC article system on .org if you can provide one. Cinq is also working on a porting vbarticles to vb3.5, have you thought about contacting and working with him to help get it done? A complex article system can be a lot of work to do by yourself... I should know :P
IMO freedom of choice (regardless of FOC or commercial) only enriches all end products and thus choices for all users.
Good luck!
