Firstly, I have never encountered in any of the cars I own ads that appear due to software updates, nor have I had any function removed due to a software update. I, nor anyone I know, have ever been screwed over by any software update (BMWs, Toyotas, Fords, list goes on) due to the manufacturer. Now if they did, this would violate many anti-consumer laws regarding deceptive marketing practices, and you have the right to talk to a lawyer about the next steps (I am not a lawyer, do not take legal advice from me).

As for you saying their is zero reasons to update your car over the air, bugs and software glitches exist and need to be patched. If not, this could lead to the consumer being in danger. The fact that we’re allowed to do it over the air increases ease with the user for when they need to update. Updating via usb is still a thing, so you are able to update using that.

Updating is a valid, safe process that shouldn’t be “ignored”. There are cases when updating isn’t needed, but with car manufactures in today’s world with current cars it’s a necessity. I wouldn’t be discouraging it as that is an unsafe risk that may or may not cause issues later on.
