"No one owes you car safety. You're responsible for not crashing - cars give you all the tools you need: brakes, steering, lights..."
Disappointing to hear this from a Rust programmer, who should really know better. Although they say they aren't even a programmer so I guess that makes sense.
The analogy is more like
"Here's a free car on a parking lot. You can take it if you want it for free. The car hasn't been inspected and there are no guarantees that it's road-worthy".
I think this is perfectly acceptable in most countries and I doubt you'd have any standing to sue if the car turns out to have safety issues.
