Kernel Maintainer Kills Philips USB Camera Support

outanowhere writes "The author of the Philips webcams kernel module has thrown in the towel and quit providing the pwc and pwcx kernel modules which make using Philips-based USB cameras such as those from Logitech and Philips possible with Linux. According to the author, the last straw was when a kernel maintainer changed his pwc module to make using the binary-only pwcx compression module impossible. It is a victory for obsessive kernel-purists but a major loss for all Linux users."

Re:"Zealotry"

The module was fully GPL compliant but provided a hook where you could attach a binary-only part (this part wasn't necessary for the module to work, it just added more functionality).

So the module was completely GPL compliant but some people thought the hook to be "impure" or something... and removed it. After it has been three years in the kernel tree. The author is right: this is a little late to make a point !

That's zealotry in my book as the module did meet the legal requirements.

Misguided

[albalbo]

I love the misguided comments in this story. In particular, I like the "most users don't care what is in their kernel, so we shouldn't care that we're taking away freedoms from all (including those who do care)".

Some comments from the guy who actually did this (http://www.uwsg.iu.edu/hypermail/linux/kernel/040 8.3/0270.html):

"Without this hook, PWC will work, but with limitations, just as it always has."
"Actually, I've got a little surprise for you. The NDA I signed with Philips has already expired a year ago. Yet, I didn't just throw the decompressor code on the Internet."

So, just to summarise, a) removing the hook doesn't stop the driver working, b) there isn't really anything stopping him publishing the code as free software. Basically, he just wants to take his ball home because he thinks he should be allowed to put hooks for proprietary modules into the kernel.

Is it the first time he's threatened to do this? No (http://www.uwsg.iu.edu/hypermail/linux/kernel/010 5.3/0365.html):

"Anyway, I am not going to debate this any further at this point. Johannes, please remove my webcam driver from the USB source tree" (May 25, 2001)

Linux doesn't need proprietary drivers, it doesn't need to compromise freedom, and it certainly doesn't need people to try to press the issue by holding code hostage. And, aside from all the facts that this guy is acting an arse, there are also questions over whether or not the hook is legal (Linus' point of view of derivative works of the Linux kernel is quite clear - they must be GPL'd), and the decision to remove the hook was partially a technical one anyway (only one driver is using it).

Yet, we are still going to get people holding this up as an example of the GPL preventing Linux from "going enterprise" or whatever. Guys; shove it - for Linux to be "accepted by business" doesn't mean that developers should bend over for whatever perversion proprietary companies want. Jeesh.
