So they hired 3 people in 2022 to copy all game files into an archive hub.
Wow.
Way more than this.
Hired them to research all the data available from all their different studios (and pretty likely in most studios wasn't properly stored so had to analize many computers from each studio) and in different formats related to how these games were made. This includes their documentation, original art and audio assets, code, etc.
Then to properly classify and document it and store it in a centralized and secure, future proof place (the cloud, I assume).
And then make possible to use in modern and future devices these documents, assets, code to compile, etc., because in most cases were made for apps, OSs, devkits, libraries, engines etc. that no longer are available or there's a very limited access and it's very difficult to use.
As an example, thanks to this they were able to provide the team who did the Twisted Metal tv show auido assets recorded for over a decade old Twisted Metal games. Not the compressed files included in the final game: the original, higher quality, ones.
Cool, can we get a way to preserve our gamesaves without paying for plus?
Yes, in your console or in a pendrive. Or moving them to other console through your LAN.
Ok, now let me change the region of my PSN account please
Their IP preservation team is totally unrelated to this.
