Brandon I don't disagree and hope more consumer demand helps alter things. I would like to have the option to use IPv6 if I want. One ISP at the street has some IPv6 in their peerings but none to customers which means it is possible. Another ISP at the street looks to be using CGNAT for customers on FTTH with zero IPv6 peering. And for those secretly taking bets yesterday. The work at the street did knock me offline for most of the day. :( Maybe it would be a good discussion point, what happens when every user is behind a CGNAT in the near future?

Today yet another ISP is running Fiber in the utility easement at the street. I checked and they do not offer IPv6 or have ANY IPv6 peering.
I have offered the hard to find IPv6 Legacy Warning stickers on my Redbubble profile. About a month before any meeting or event I see a bulk order for Amish IPv6 stickers designed by Phil Benchoff and hard to find post Google+. I have the markup/profit set to the lowest setting and have made maybe $8 over 5+ years.

Ranting a bit as I have four ISPs boxes at the street and two of them do not have IPv6 in 2025. Converting my frustration into finding Phil and sending him some coffee money.
Until consumers care, bulk-subscriber driven residential ISPs probably won't care. They have to provide IPv4 anyway, and most of the startups are stuck running CGNAT to do it already, so IPv6 is just another operational hassle for them.
I don't like it, but it's the way it is.
The major content providers could do a fair bit on this front. They could start by supporting IPv6 at all (sadly many don't), and for those that do support IPv6 (which is a lot of them - and thank you!), they could nudge their customers into getting it enabled on the grounds that it may improve their experience (which is true since it can and usually will bypass overloaded CGNATs).
OTOH, I just had an issue where I ended up disabling IPv6 for a customer and improving their all-important speed test metrics by 50% across the board to all test providers who support IPv6. My peering is pretty symmetric, but I assume their (older but far from obsolete) router has hardware offload for IPv4 but not IPv6 since that seems to be the bottleneck in all cases. Obviously I could tell them to get a new router, but we know how that's going to end.
