Mother of god, I knew Uncle Bumblefuck was based but I had no idea he was that based! Which video(s) did he swipe at Linus in? I've got to see this for myself!
Data hoarding is a thing, not just for pr0n but also for more legitimate purposes (beyond "torrents of Linux ISOs"). The internet is no longer a reliable archive of content, especially media. Youtube nukes videos all the time, all its competitors either collapse soon after inception or are just unusable (and none of them ever gain any traction), and of course with all the streaming services (Netflix, Disney Plus, HBO Plus, Hulu, whatever) you own nothing and don't get to keep anything you view. If the service dies or decides to "delist" content you liked, tough noogies because it's gone for good.
So plenty of people (myself included) download local copies of anything they might want to watch or listen to more than once, be it movies, TV shows, Youtube videos, music, audiobooks, podcasts, etc. They also keep local copies of software that might disappear one day (in my case, much as I hate that I occasionally need them, I keep historical copies of all of Microsoft's Visual Studio releases all the way back to Visual Studio 6 and every subsequent version all the way up to the current version (2022), along with every edition of Windows, Windows Server and even Windows NT).
Not to mention video production takes a fuckton of disk space. Raw 4k footage is absurdly yuge. I can imagine LTT easily gobbling up a few terabytes of storage space just producing a single video.
And of course lots of people keep pr0n. Lots and lots of pr0n.
