If they want to turn off their router's IPv6 firewall now or in the future, they're free to do so, but it was an active choice on their part making it their responsibility.

Even if you disclaim that responsibility and state its limits when you 
chose to provide one limited component of the "security solution" , if a 
customer has a perception that you are taking complete responsibility, 
and they get breached, they can waste your time and money by taking you 
to court, encourage a class action against you etc. IOW, doing a small 
amount of limited security on your customers behalf creates an increased 
business risk.
