As the update only affects infotainment and not critical systems, it seems like a reasonable tradeoff to me. Just because a car can fail in ways that kill people doesn't mean all parts of a car are equally critical.
This isn't true. If you look at the release notes for any of Rivian's updates they all include vehicle related firmware changes. This is not simply infotainment.
Beyond that "infotainment" includes driver critical information - like the speedometer which, for many affected, means there's no working driver screen.
