Comparing games on itch to revolutionary creations in art and entertainment is very weird. You're not preserving much by reuploading someone else's small itch game. Also something most people don't know, in the terms and conditions of buying most games you're agreeing to not resell them. That includes game disks that most people sell at yard sales, so the idea of reuploading someone else's game has been viewed as negative for awhile. I mean, I saw someone reupload "FNAF: Into the pit" on here a few months ago. That's like a $20 game, and the user just uploads it for free. That's literally pirating.

I'm not a native English speaker, so maybe I didn't express myself adequately.
I'm not comparing classical works of art to indie games. The mention of works by Picasso or Mozart is simply to emphasize the importance of preserving our past. Period.
When I say preservation, I don't mean piracy. I mention that, but maybe I wasn't clear.
