At least in the UK, it's infamously only Earthed if you use the long extension cable (instead of plugging 'wall wart' in directly) that they no longer supply.

That argument doesn't work here, all are 3 pin. It's a conducting third pin too, even though it's NC, which isn't even compliant. My suspicion is that it's way more noticeable on European voltages (frequency could also be a factor?) so they don't notice in the US and don't care. I have a few products that do it; they're all US companies except one Japanese (slightly lower than US even at 100v, and product primarily sold to US I suspect). My Framework laptop will shut down if it touches a charging but un-Earthed MacBook.
