I don’t think they were talking about access to the network.
“The inside of the network stay anonymous” sounds like they are talking about internet access to the internal network.
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
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.
