If you knowingly share your connection with someone else and then they go on to do illegal activities with it, you can be held liable.
That article doesn't actually cite any legal precedent for someone being held liable, just a case in 2011 where the guy was found not guilty. It just says you could possibly be liable.
It would be like charging the ISP because someone did illegal stuff.
