They didn't just know about it, they actually said they didn't want to perm disconnect accounts they were told have been repeatedly infringing because they didn't want to lose the money those accounts would bring in. They screwed themselves by talking about it over email (including saying outright "Fuck the DMCA"). No ISP is happy about the fact that they're forced to spend significant amounts of time and money working as "copyright police" for the media industry for free, and they aren't happy that (so far) courts have insisted that they need to permanently disconnect people from the internet over nothing but unproved accusations from questionable sources, but it was a bad idea to talk openly about that in email because all of that was later used against them in court.
