I think the implication that while net neutrality to some degree[1] ensured neutrality in carrying much data indiscriminately, it did very little to ensure neutrality at the edge (that is, Twitter could decide it wanted to silence any minority or majority with impunity). So if an edge provider can discriminate what is allowed, does that undermine the ideal of net neutrality?
With Goog-Twitt-Face being the triumvirate of gatekeepers I think this concern deserves some consideration.
