The responsibility of the content published should be shifted from the author to the platformHow is the platform going to know what's legally published and what isn't? In some cases I suppose you can work with an industry, like YouTube's Content ID for music, however even with Google's resources Content ID still has severe glitches[1] (should they be legally responsible for false positives too?). Otherwise what, hire an army of mechanical turks to manually review every single thing that's uploaded?
At best I think under this kind of system you're going to get a stagnant landscape where only corporate giants with deep pockets and/or industry connections can create new innovative products. There's going to be no more upstart Instagrams, Snapchats, Soundclouds, whatever if the company can get sued into oblivion if some rando takes a pic or uploads a snippet of copyrighted material.
