From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

If computers connect to others through the internet, the IPv6 address can reveal how many computers there are on the local network, and if certain traffic to different destinations are coming from the same computer, but also if one of the computers has gone offline but then resumes from sleep/hibernation.
To me their comment means they want to avoid that, and I agree, I want to avoid that too. To fix these, I would need to configure NAT on my router for IPv6.

Yes IPv6 address privacy extensions help somewhat, but

computers won't use a different v6 address for every distinct destination, they will just start using a new one from time to time
computers won't stop using the old v6 address immediately after wakeup

With v4 addresses these did not really matter, because everything was being sent from the same public IP, and and outside observer could only see what a "network" is doing collectively. But with v6 an address identifies a computer, across websites/services. Even if it's just for a "short' time, even if the address is randomized.

If you want privacy, you need some kind of VPN or onion routing. Even if everything you list were correct, the difference between IPv4 and 6 for privacy would be marginal.

I don't think this is so black and white. I'm a regular tor user, but so often it's not worth it to load webpages through a dial-up connection, and then there are the sites that block access for tor users for some reason.

Even if everything you list were correct

Which parts weren't?

I disagree
