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.
