I can get behind some of those criticisms, they are valid. However, a modern EV shares a lot of similar parts with a ventilator, including air purification and flow control, temperature control, pressure sensing, etc etc. And if they partner with someone who knows their shit, maybe something good can happen. I.e. a simple reliable enough ventilator that doesn't tap into real medical part resources to make. They actually put effort into some amount of redundancy and safety (notice an entire VCRight ECU used as a watchdog on whiteboard). This is not an average Arduino/Home Depot build.
