In the beginning we used to exchange cassettes. You would have a boombox with two cassettes. You would play one while you recorded on the other. Then you gave the cassette back to your friend. Next was the VCR with the big ass cassettes.
Then you would do the same with floppies, then zip disks. Then one day CD recording was a thing, then DVDs. Then thumb drives and now portable HDDs. Basically the cheapest form or recording is always the most popular way for people to share stuff.
The only ones who don't want us to share are those who want to make millions by never innovating.
