So on a morality point of view, I've downloaded epubs of books of an author where I've previously bought copies of their books multiple times, either because the originals wore out or I gave a copy away. I still have copies on my shelf or in storage, I just want to have copies on my Kindle.

I've bought things (or had bought for me) things on VHS and DVD formats and no longer have a player for either. So yeah I downloaded stuff I wanted to watch again

There are things only available on DVD and not available to stream. There are things that were available to stream which have since been removed and have been taken down. Why not pirate stuff to watch it again?

For a long time the Beatles weren't on Spotify etc. I had their stuff on their official paid for tapes growing up, then on CD when I was older. So in the interim I pirated it when I lost the original digital rips I made from the CDs. And until they release their mono albums officially I'll be hanging on to my pirated copies.

Notice a trend in the above? I very rarely pirate new media. But I treat the internet like an archive (I've not even gone into the stuff that is no longer available anywhere except YouTube or piracy). Quite often I've paid the creator('s masters) more than once for their work. I feel no guilt.
