I wouldn't decline this idea so fast, i think he
made a valid point.
If you watch todays software market, especially the battle between the
OSes, you can see Apple as well as M$ aquiring so-called
"Killer-Applications" which shall force people who need that Apps to
move to their OS. Especially what Apple did with Emagic Logic is a
perfect example.
Now if you allow your Open Source Applications to be ported to this
proprietary OSes, you strengthen this behaviour and weaken the Open
Source Movement. People will get your software but will stick with OSX
or whatever cause of this called Killerapps.
And i dont think GPL is not so much about not ppl letting you force to
use special software. IMO its more about sharing and passing knowledge
(great both in a technical but also social/political way) and do
better
software by the benefits of it.
Actually i dont know if this new form of GPL is a good idea, but i
guess
its worth thinking about it, as you still have the
goods of opensource
but just decline the possibility to support Non-Opensource Systems.
My point exactly :-).
Just to add a bit onto this issue is that we could still support
non-opensource systems, but they would need to purchase the software
(see my other e-mail with the Trolltech as an example).
