This Service Could Dismantle Copyright Forever, article.
So what's to stop Mega from going down just the way Megaupload did? Mega's privacy, which is a no-foolin' stroke of genius. See, all of your files are encrypted locally before they're uploaded, so Mega has no idea what anything is. It could be family photos or work documents, or an entire discography of your favorite band. Poof: online and easy to share. And importantly, Mega doesn't have the decryption key necessary to get in. See? It's a masterstroke of copyright subversion.
