A comment on IPv6 Is Hard. Parent comment

Devices behind a firewall being routable with IPv6 doesn't mean you're allowed to connect to them by default. And if you want to, you have to explicitly allow that on the firewall. Just like you would open a port and redirect it with IPv4 before. Only with IPv6 you don't have NAT and a redirect. Some people need it and some don't. Again, just like with opening ports.

How many users know how to "open a port"? UPnP exists because people don't want to deal with these things.

What's your point?

  |              | IPv4                                | IPv6                                |
  |--------------+-------------------------------------+-------------------------------------|
  | With uPnP    | Unsolicited connection goes through | Unsolicited connection goes through |
  | without uPnP | Unsolicited connection blocked      | Unsolicited connection blocked      |
It's exactly the same in IPv4 and IPv6 just like FeistySkink was suggesting.

Please reread my comment, it seems like you're just pattern-matching to arguments you've heard others make in the past and assuming I'me saying the same thing. I'm not. See sibling comments for elaboration.
