  Think a little broader. The IPv6 Privacy Extensions just shield your mac address unless I've missed something. Let's say I'm a transit provider [like Google]. Right now, I see TLS traffic from your public IPv4 address to another public IPv4 address. I have no idea how many devices are behind those public IP addresses. I can maybe combine a few assumptions with my browser-based tracking, but it's difficult to identify you in apps I don't have control over. Switch to IPv6, now I know exactly how many devices behind your firewall are talking and how many devices you're talking to. Even better, I can combine this with a browser-based tracker and I can see what you're doing in apps I don't control. I first identify you with the browser and what IPv6 address you're using. Then as you use other apps that I can't spy on, I just have to look for your IPv6 address in my transit traffic to figure out what you're doing.

    A solution could be a Firefox browser extension that allocates a huge number of v6 addresses to your computer dynamically from your LAN /64 or /56 and creates fake garbage google usage data, so that google can never build a profile on you based on v6 address (if you are this paranoid). Or... just stop using google and use uBlock Origin to block all Google domains.
