I did not realize at first sight that this is an old article. It was standardized in the 90s and supported by most interfaces since the early 2000s but does not seem to be working properly as of today in terms of adoption. A big problem today regarding Ipv6 is the still missing auto configuration on most devices and router sided problems like don't sending out router advertisements with the prefix. Then there are other problems like no default gateway set. Technical skilled people are able to get Ipv6 running on their pc, but not the average guy.

Problems get much bigger on mobile which represents most of the worlds population digital presence. If everything properly configured Ipv6 works over ones own network normally as on a pc. But good luck with mobile data. Changing APN settings on android to Ipv6 does often not work / not supported by the ISP.

Almost half the world is using IPv6, according to Google's traffic statistics. In some countries it's 60%, 70%+ and I'm sure includes plenty of average guys.

This is mobile phones dominating that number. Almost every 4G / 5G phone right now uses a dual stack IPv4/6 connection. This is not necessarily problematic but home broadband is still lagging by a lot. I sometimes never get a prefix assigned. I have to redial PPPoE as IPv6 link uses IPv4 session. It's not plug and play for home broadband unless you use their modem router combo which has other issues.

Good point but there is still half of the worlds population missing which is due to missing auto configuration / proper support by the ISP. And I would guess that these numbers represent connections from home networks and not from people on the go using mobile data.

Cloudflare has data on this, but I'd like to see filters (is ipv6 and is mobile, for example).

In my experience with consumer internet service and cellular service, ipv6 (when available) just works out of the box and you don't even have to notice.

Huh, I haven't seen that issue with RAs. So far, my SLAAC deployment is playing nicely with my endpoints. About 40k devices, all BYOD. SLAAC seems like the only way to make this go. Because Android still has no intention of implementing DHCPv6. :(

I'm not going to defend ipv6 since I also think it's bad, but in this day and age autoconfiguration works perfectly.
