> it’s disturbing to see people clamoring to deny others their freedom in a FOSS context
How does "allow building Linux to be IPv6-only" somehow "deny others their freedom" exactly? I'm willing to wager most distributions will still be dual v4+v6, but if they aren't, isn't that something for you to bring up with your distribution rather than that the kernel just allows something?
Coupling this patch with language about “legacy IP”, along with the follow up comments from the person who submitted the patch, it is clear that the submitter is hostile towards IPv4. I also see hostility towards IPv4 in the comments here and other similar discussions.
I have no problem with allowing optional IPv4 or IPv6 only builds as long as both are kept well-maintained.
