This Lex Friedman interview is pretty explanatory on the topic of responsibility.
A couple of highlights, which point to Comma being at minimum more responsible than Tesla: Comma doesn't advertise itself as anything beyond L2, unlike Tesla; Comma doesn't fuck up eye-detection, it refuses to cooperate with a driver who has their eyes off the road.
Because from the scraps that I've managed to put together, he seems childish and irresponsible.
