Of course piracy preserves old games. Also piracy is not a problem when it is miniscule. The issue is when piracy becomes the norm, so that these companies will be pushed towards more locked systems (consoles exclusives) and abandon PC. Some may even call for androud style locking up on PC.
The problem is true 5G is high frequency and very low range, requiring towers everywhere. Also realistically we don’t even need these speeds on mobile devices, what it should’ve been is a better 4G with more reliability and better performance in crouded areas.
