IPv6

My network is entirely v6, I tolerate NAT64 given the current internet landscape but every service I can cut out that needs NAT64 the closer I can get to disabling NAT64 which is ultimately my goal. Still a long way from that but I'd like to get there. Additionally the NAT adds latency as it resides outside of my normal network path. I've also taken up a policy of not using new services that don't have v6 if at all possible. That was a key factor in deciding what lemmy instance to use. While it might not matter to you it's something I look at.

To be honest lack of IPv6 support is a petty reason not to use them

For people like us (IPv6 advocates), moving away from IPv4-only services is just like voting with our wallet. Well, except that the flow we are looking at is not money flow, but internet traffic instead.

Obviously such a movement is not going to make a huge dent in the grand scheme of things -- very few people care about the internet protocol they are using. But the idea is that it will eventually end up in someone's log that, a lack of IPv6 support is driving customers away and/or implementation of IPv6 support is attracting new customers.

Also, it doesn't hurt anyone else except us when we purposefully move away from IPv4-only services even though the IPv6-capable services are worse ;) Anecdotally speaking though, that's a rare case.
