I don't think the meme was ever supposed to mean it's safe to rely on the internet to preserve your data. Instead, it means you should never assume you have the power to delete data once it's out there.
Then there are examples like Marion Stokes[2] who recorded 71000 tapes over 30 years.
Fast forward to today (ha ha), and I do think there is some justification for downloading 'pirate content' for archival purposes. In the same way that I think LibGen is a very important project even if it angers some.
To be clear, I believe in buying the items I'm actually going to read or watch to support the creators. Not just pirating everything.
