> My local ISP (US Internet, soon to be part of T-Mobile Fiber) hasn't enabled it, even though the CEO has said on Reddit for years that it's a priority. Now that they've been acquired who knows if it'll ever happen.

Being a priority doesn't mean it's high priority. It could be a priority, but the lowest ranked one, so other stuff always comes first. :P

T-Mobile wireless US is pretty invested on IPv6, so if they take over the network, they may well push it.

It "finally hit the top of the project list" two years ago so we'll see lol.

It's "T-Mobile Fiber Home Internet" which looks to be a bunch of local ISPs they've been snatching up, so we'll see what happens. USI's customer service and reliability have been amazing so hopefully that doesn't get screwed up.
