Just piss-poor engineering to use something with about 100x the processing power that's needed for the job - an ESP23 would do just fine.
And if it wasn't enough of a toy - the Hypervolt also has a bunch of WS2812 LEDs inside to make pretty colour patterns :palm:

Lacklustre engineering indeed, although it is the sad reality of the market. Computing has become so cheap the developers became complacent, and users became forgiving to have to restart stuff due to a lock up or something else.
I am happy that not everywhere is like that. Lately I have been working in the Bluetooth LE world and the common narrative is: an update or functionality that requires you to reboot or re-pair is absolutely unnacceptable - go back to the drawing board.

It isn't the fault of the RPi if somebody uses it in an entirely inappropriate manner. It is not marketed as an OEM controller to go into an EV charger. It is marketed as a low cost educational computer. The fact that it has sold many times more than originally anticipated and found itself used in things it was not originally intended for is beside the point. If somebody designs an Arduino into a space rocket that isn't the Arduino's fault.

That's exactly my point: you don't know. Most users, if you go by what you see on the web, assume it's a Linux bug. Usually it isn't, exactly because most of the peripherals on the Pi core are connected via USB in the first place. The nature of USB bus is such that packets are not supposed to be lost (or rather, acknowledged as received but dropped on the floor anyway), and some drivers just cannot recover gracefully from such losses. The common end result is a completely locked up kernel, requiring a power reset.
It irks me, because it diverts blame to those who are not to blame.
You describe failures that would be unacceptable to me, yet you describe your Pi experience as "fantastic". I wonder what words you'd use if you were using actual known working hardware, whose support is in upstream vanilla kernels? (Most people tend to completely forget about it: when something works perfectly, it becomes invisible. I've maintained servers whose users completely forgot they existed, even though accessing them daily.)
So, I'm not sore about Pi –– it is what it is, and even I have some due to the price point and camera module availability ––, but about how their users don't know nor care if the issues they live with are due to hardware or software.
How do you feel when your inane coworkers failures are routinely attributed to the entire team? Not very happy, I'd imagine. In this case, the stink follows everywhere, and switching jobs won't change anything.

No wishing to take the discussion away from RPi and their forums, but I was reminded of a expensive foray into CD burning I was involved in nearly 25 years ago. I already had server class SCSI II gear for burning CDs and tape backup and HDD storage which worked well, once setup properly.
I then helped someone with getting a very early model external USB CD burner working with a Toshiba laptop running w98. What could go wrong? CD burning -had- to be done without any interruption throughout the whole process. Of course, it bombed regularly.
After blaming the CD drive manufacturer IOmega(?), then MS (cos why wouldn't you?), it turned out to be a dodgy USB controller chip in the laptop provided by NEC, who denied any problem. Ended up being resolved after a class action.

The Hypervolt uses a traditional RPI. Wallbox doesn't, they use an RPI compute module which is fine:
