It's something I've only recently been made aware of as well. Shocked we're not seeing more push for ipv6 everywhere given that it sounds common enough. If I don't have an IP address, I'm not getting the Internet I'm paying for; I'm getting access to a network that happens to itself have a connection to the Internet. Not unlike some of the BBS's in the early 90s which had Internet access -- I might be dialed in, but that didn't mean my computer itself was on the Internet.
I now live in a "western" country and I have CGNAT. It is extremely common here. On the other hand, my ISP (largest provider in the country), in a "developing" country, gave me a public IP so I think there are more moving parts.
I don't think it's sarcasm, I didn't know this was a thing either! At first, I thought OP was writing about their mobile connection.
Some carriers in my country have recently started to share the same IP between 4 customers, each having a port range (1-16363, ...), but you can always request a full IP for free.
That explains a lot of the sentiments I've seen on HN then...
I, unfortunately, have been on CGNATed residential internet since 2016, though I used to still get a public IP on request (they stopped doing that though.) I live in South East Asia, for context.
Without IPv6 my only choice would have been relying on a centralized service like Zerotier and Tailscale.
I converted from residential-class to business-class cable a few years ago. In both cases, I had routable IPv4 addresses.
I was just looking at flipping back, but now it seems the default for new resi accounts is CGNAT. They say they'll give me a real IP upon request at no additional charge, but it's anyone's guess how long that holds out.
In Sweden CGNAT was not a thing for a long time, the large incumbents still have their huge blocks of IPs so its "just" go to them if you want a pulic IP. Apparently smaller ISPs do use CGNAT, so its fairly common.
Me as somewhat of a nerd, even doubt if I need a public IP, seeing how cyber security is looking today.
I think CGNAT is the default for new connections in .au, since about 5+ years, at least among "younger" ISPs that popped up around the national broadband network crawlout.
You can generally request to get off it though, at ~1-5$/m extra cost.
In my experience they charge for a static IP but not to turn off CGNAT. Obviously depends on the isp but I’ve tried a few.
One of them I had to call phone support and they asked me why I wanted to turn it off. I said I wanted to run a server and they turned CGNAT off on my account.

I can't tell if this is sarcasm, Poe's law and all.
But if you are living in a Western country, then you are probably blessed with CGNAT-free residential internet.

They don't do IPv6 at all.
