I'm just trying to figure out where this ethical concern starts and where it ends. It's unethical to upload a movie on-chain in plain text, okay (I personally disagree, in the same manner I don't feel guilty for other people's transactions). It's apparently not unethical to upload it unencrypted? Not until you find out what's in that encrypted file? How about links? Is it unethical to store an onion URL that points to a totally illegal place?
Anti-piracy advocate groups would say all of those scenarios are all unethical, but then again, you'll get a different response from everybody, including from the people who pirate that stuff in the first place.
Nevertheless, there is what seems like a doctrine of stuff people consider universally illegal (which includes things obvious enough that I don't have to mention).
