> But a lot of piracy happens with publicly downloadable files, which MEGA can definitely decrypt and search for copyright violations.

This is straight up wrong. Mega cannot decrypt files and search for copyright files just like that. They need to have the key for that. I have shared a lot of copyrighted stuff on mega and the links are still available publicly but in closed forums( still active ). mega would've taken it down a long time back if they knew what was in it. They can only take down files when corpos notify them with the base links to the file. If they don't it stays up.

So you're saying the file URL for publically downloadable files contains the decryption key?

Usually but not always. If omitted from the URL parameters then it has to be provided for decryption.

I once downloaded copyrighted material to my drive. I never gave the key out, yet a few days later it was no longer downloadable due to said copyright violation. Has Mega's encrypted design been audited?

[shmde]

Did you import the copyrighted material from someplace else ? The base link + key was given to you by somebody else ? If YES then copyright holder got hold of the base link and notified mega. This is common.

OR

You uploaded copyrighted material to your own computer to your own cloud, downloaded it and the file got taken down ? This is not possible. If yes then I am in trouble.

Most likely the former. It was a while ago and I barely recall how it happened.
