If the systems were properly documented for the owners I seriously doubt there would be a problem. Give people a USB stick with docs, sources and signing keys and those who can make sense of them are probably smart enough to hack responsibly.
No way. The carmaker cannot guarantee emissions, safety or its operation if tampering is permitted. I think they should stop at voiding the warranty, though, and not move on to making threats or legal actions.
