It could be that the GPL license increases software adoption.
If Thesis was GPL, there would be a lot more Thesis powered Wordpress blogs out there. I think Matt attributes a lot of Wordpress' success to the open community the GPL allows, which evidently leads to more and more people using Wordpress as the platform of choice.
And like Matt said, if the members of the Wordpress community start thinking that its OK to not use GPL, it could be slippery for Wordpress as it will effect growth.
