I could be wrong but I dont think that RSA's piracy is second lowest in the region because of intervention by the law or any anti piracy actions.
I mean how many times have you heard about piracy busts?
Its simply because we dont have fast and cheap internet. At the moment piracy cost pirates money due to our expensive internet. If you download anything it cost you close or even more than actually buying it from a shop..
Unfortunately we ALL either are or know people that download, copy or buy pirated movies,series,games etc.. Similarly do we all know thieves that steal money? I think not (hopefully). Thus piracy I would say will increase as our internet get cheaper. It will get alot worse before it gets better because face it, our government....onions and beetroot,.. Ivy...ICASA..
Then again some argue that piracy is a necesarry evil, almost like advertising or getting people hooked on media first. Then when they change their ways they are very supportive and active buyers of legal media.. Nevermind the losses due to piracy, the profit from movies and games is still HUGE and increasing. But thats another discussion.
