Sometimes, I wonder what the Archive stores in their non-public repositories. Just waiting for the day when it's safe to show the world.
I personally don't really care about achieving anything. Why is this such a big thing? Why would we want to achieve all the APKs? There are too many of them lol History? Memories? Who cares, we're all going to die lol And with the qty of APKs, only 0.00000001% of them will ever be dug out of the archives.
It is hard to know what APKs (or anything really) will be interesting to people 30 years out. Archiving all of them gives our future selves a chance at finding what they want to see.
Here is an example pulled from a discussion I once had. Someone was looking for a really obscure feature phone game from the late 90's. I had played the original game on original hardware and commented about how bad that game was and that they weren't missing anything by not finding it. Their reply was essentially "I don't care if the game is any good, I really just want to experience what was like," which made sense to me after I heard it.
Anyway, the game was so bad at the time it was released that I doubt anyone felt like it would be worth revisiting in the future. And yet, 25-ish years later, they would be wrong.
Why did they do it? No idea, and there is no official response in the forums, despite users complaining about its removal for over a year.
