I think they've done a few things since then.
1) Better training to their reviewers to recognize the main sources of piracy like PluralSight
2) Requiring ID from many new and existing instructors to prove they are who they say they are
3) It's easier for anyone to report copyright infringement they see, since they've added a flag icon (report this course) on every course.
They follow the DMCA process, and it's pretty easy to get your content taken down. Sure, if you report something on Thanksgiving day, you might have to wait until Monday as the legal department isn't standing by 24/7. But I've reported piracy to Youtube and it's taken them 3 or 4 days to reply as well.
In short, it's the Internet. Yes, people steal your digital stuff. Yes, it's up to content creators to police that. Yes, it's tiring as a content creator to chase your stuff all over the Internet. But it's the Internet.
