Words like "buy" "own" and "purchase" have a specific connotation. These licenses upend that.
I am part of the Rock Band video game community. That scene is covered in the use of "buy" "own" "purchase" terminology. Now, granted, Harmonix went above and beyond when it came to ensure they had solid licenses, so even though today they've been delisting DLC because their original license to distribute the songs to new customers has begun lapsing, they also went way above and beyond to ensure that people who bought content in the Rock Band 1 days would still be able to play them across the whole same-console library, so much so that anyone who bought RB1/2/3 content on either Xbox 360 or PS3 were able to also play those songs on Rock Band 4 on Xbone and PS4. I think there might have been a small fee in some instances, like when exporting disc content to newer games, but outside of that they went far beyond what most companies do when handling licensing (and this is music licensing, one of the most notoriously hairy forms of licensing that one can do).
These licenses are also re-downloadable by anyone who "bought" them, at least until the platforms entirely shut down the legacy console access for re-download of content that was paid for. Fortunately, we as a community also have all of it preserved without the DRM in preparation for the day when you can no longer even re-download content you paid for. There are also tools that let you copy the content files directly from your console (where possible with or without mods) and convert or decrypt them yourself.
