I think the lesser popularity of piracy with the younger generations is somewhat less about intentional takedown-based anti-piracy efforts and more their preference for mobile devices and the "pirate" options failing to keep up while the legal streaming services are worlds better than they were 10 years ago. Apple not allowing torrent clients on the app store definitely helped, though. That comes back to the broader narrative of the war on general-purpose computers: perhaps the most effective anti-piracy effort of all has been selling people devices that run crippled OSes like iOS and Android instead of Windows.
