Other car manufacturers update their cars all the time. Some OTA, some you have to take in to the service center, but that does not mean they don't do it. The easy to steal Kias is an example of a recent recall that just required a SW update via service center. My ID.4 just got an OTA update last week. Tesla is showing negligence for not updating a service that is still in a lot of vehicles but they don't actively sell anymore.
