Yeah, but fortunately or not, it's possible.

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?

Putting censorship resistance above personal ethics is another thing I like about Bitcoin.
