Hi!
I am not sure where in histrory you will find that I have ever advocated for dual licence, since it is well known that I do not for work which I personally do (aka if you check you will find that I lean toward BSD).
Also, I believe people are free to do whatever they like with what they produce. No company doing original work should feel that they have to open source it.
What I object to is Richard's comments which I find counter to the notion at what is at the center of notion of the gpl. I seem to remember the fsf suggesting once that developers assign copyright to them to block dual license strategies. Richard's current statement seems at odds with this.
You are welcome to do whatever you like with whatever you write Bruce, but I wouldn't suggest that other developers contribute their work to you, just so that you can change the license and make a buck off them.
