If we're to keep pretending we live in some sort of free market, we need financial neutrality, among all payment processors.

I wish these articles would bring up the Fair Access To Banking Act, which could solve many of these problems if it can get passed. It seems to have widespread Republican support, which is enough to get it passed in the House. But it could still be killed in the Senate if the Democrats decide to filibuster. If the bill becomes popular in the media, there's less of a chance they'll shoot it down.
