In my country it is illegal to share, but not illegal to download, since when consuming you’re not meant as a websurfer to know the source of that something. Should that law change, it cannot retroactively affect something that happened in the past. So I don’t plan ever to share anything publicly, but only the very few things I’m very passionate about to the point I want to share them with communities of friends which you can access through invites only. Sharing a back up copy with your friends is not illegal either even if the EULA or whatever says it is, unlike for example in the UK.
I was specifically asking about cybersecurity in general.
it would be perfect if the downloadable PSN catalogue was complete, but there are so many games that are available disc only or can’t be downloaded directly from the PS3 itself, so you need to bring games from your pc to your ps3.
