It is important to view the pwc/pwcx driver/decompressor in the context of all webcams which rely on them. In addition to the Philips family of webcams (11 models), the following make/models also use Philips chips, necessitating use of the pwc/pwcx driver/decompressor:
Askey: VC010 Creative Labs: Webcam 5, Webcam Pro Ex Logitech: QuickCam 3000 Pro, QuickCam 4000 Pro, QuickCam Notebook Pro, QuickCam Zoom, QuickCam Orbit/Sphere Samsung: MPC-C10, MPC-C30 Sotec: Afina Eye AME: Afina Eye Visionite: VCS UM100, VCS UC300
This, as we say, is not "chopped liver"; neither are the multitude of Linux users who presently use these products (or Windows users who contemplate upgrading to Linux). Moreover, the manufacturers of these products are not going to stop using Philips chips.
At the same time that the ideological-purity of the GPL must be maintained, so, too, must pwc/pwcx-dependent hardware users not be disenfranchised.
My $0.02, YMMV.
