Under what circumstances does the first amendment guarantee anonymity?

As much as I dislike twatter, for once I agree with them as I’m a firm believer people should be able to leak things as minor as concept art or unused game art.

Back in the day, journalists went to prison to protect their sources. It was considered a rite of passage or a badge of honor. I highly doubt anyone at Twitter is willing to go to prison for their sources.

So are they now a publisher? It seems they want to have it both ways… you are either a platform provider and not responsible for the content… or you are. Want to protect people … be a publisher with everything that comes with that.
