This is a reasonable criticism, but it also feels a bit like the circular argument used for the TPP: "You're talking about the old idea, you need to respond to the new one we won't let you see!" I don't have an example of ongoing collusion, but a week before the wage fixing news broke I couldn't have cited that, either. I could probably muster something about coopting web standards organizations or hypocritical stances on net neutrality, but it would be weak.

I didn't mean to attack Walt for saying "alleging", and I recognize he's talking about consumer-facing issues anyway, but I did think it was a relevant historical note that this was very recently more than an allegation.
