Hey, how awesome you live in an area where you have a choice of ISPs and can dismiss one that doesn't meet your spec, rather than having to simply shut up and eat what you're served!
Sorry, IPv6 is absolutely not the hill I'm going to die on.
Those billions can move right along doing what they're doing. They don't bother me; I don't bother them (other than you, it seems). Considering how "IPv6 exclusive" has worked for the last 25 years, I'm quite confident I'll be dead before I reach the point of caring about it (and even if I make it, I'm equally confident I'll be able to manage both stacks).
This sort of tiresome sophistry really gets old. "But what about camgunz nearly religious need to pretend IPv6 is the One True Way and all others are heretical" is not more relevant to the wider world than "but what about kjs3's ISP".
[1] Emphasis on "that I need". I'm a network engineer and architect. Passed tests even. I've done IPv6 in prod, and I can contrive all sorts of "that only works if you're IPv6 only" scenarios and have had to work around some of them. They aren't relevant to my ISP or me.
I can't take seriously the claim that someone would literally refuse to move into an apartment purely on the basis of not having IPv6 support. Bad internet in general? Sure, that's plausible; I work from home, and like I said, the outages were annoying, and if there were no decent speed options my (now) wife and I might have ruled it out? But literally just the lack of IPv6? That's an absurd reason to pick another place to live entirely.
if verizon charges to connect the building and couldnt make an agreement with the owner. or maybe owner has non financial reasons (laziness & indifference) for denying them. or maybe some operational reason verzion wasnt confident in ability to install
