Yeah, that’s my biggest concern as well. For example LetsPlay. They had a controversy in which one primary Minecraft player was fired and removed from the group, and I think a couple of their videos were scrubbed, even though the vast majority of content in the video was good entertainment.

There are also copyright and DMCA claims ruining any YouTuber’s video, entertainment value and monetisation, including Google bending the knee to corporations that don’t actually have the right to claim any content… There are a lot of reasons for wanting to archive the internet, mostly state/corporate overreach
