This is perfect for me, who want to avoid Chinese-branded devices as much as possible.
If you avoid Chinese-branded devices you should doubly avoid US-branded devices. See National Security Letters and Room 641A as a small subset of why.

The heat pump will pull heat from inside the house? This sounds terrible for efficiency in winter, as you will need to reheat the room
There are systems (like the sanco2) that use an indoor/outdoor pump.

Sure, but lots of people have some point of the year they want cooling.
Even during the heating season it's only worse if you're heating the living space with something _worse_ than what you're using to heat the hot water. If you have a heat pump for room heat then you're moving heat from outside, to in the house, to in the water heater.
If you're heating the room with electric then in the winter it's no different than using an electric water heater (100% efficient).

The best investment in my comfort and upgrading my home was two redundantly configured Navien continuous water heaters.
Never worry about running out of hot water ever again. If I’m gone on a trip for 2 weeks my hot water bill is zero. Due to having overcapacity, whenever I have guests staying with me no one ever has to worry about simultaneously using showers or any other hot water at all. I run out of water pressure before I do heating capacity.
If one breaks I just schedule a repair or replacement for weeks in advance and have to limit folks to 2 simultaneous showers at any given time. Hasn’t happened yet.
I will never go back to a tank based water heater unless outright forced into it. It’s one of those “TiVo like” upgrades to your lifestyle you never knew you needed until you have it.
Certainly not cheap, but also not prohibitively expensive if you can find a competent installer who doesn’t overcharge.

You mention other advantages, but money isn't one. You're limited to 100% efficiency with tankless.
Although an idle hot water tank can waste ~70W (~1.7kWh) of power, this is way more than made up for by using a heat pump. Plus tankless strains the grid a lot more than any system with a buffer built in.

Yeah this sounds disingenuous. I can also see my heater to 70C if I want, that does not increase its size...
Why do you care what size it is though? It's only the capacity that matters. For example a tankless only has a few gallons inside, but that doesn't limit how long of a shower you can take.

There is also the change of location here. In normal times, it wouldn’t matter where in the world a company is based but moving “entirely to the US” is just not a good look these days.
It is rather unfortunate. I haven't seen them mention moving manufacturing or their 'Arduino offices' (have you?), but even still I'd rather not support a country threatening to annex my homeland.

"Oh no: There's metal satellites falling from orbit! Also: wanna buy a metal coin, they were sent to the edge of space!". I find the juxtaposition more amusing then I probably should.

Wanna really make their day? Pay with cash.
That's really more of a "Want to pay more than your fair share of taxes? Help them commit tax fraud".
Cutting Google out of the mix can be seen as a net positive for the community. The same can't really be said for taxes that go to your local services.
+11 and +4 seem check-digit-y
From the limited dataset it looks the last digit comes from:
last digit = (<sum of previous the digits> + 2) mod 7
