That was Randy Pitchford, the Borderlands guy.
As for Magneto, I believe one of the changes Marvel has introduced to their history (in part designed by Waid) is that, to keep their timeframe working, instead of real wars like WW2 and Vietnam as being part of characters' history, there's going to have been a nebulous, fictional war against a fictional country that will have permanently been around 15 years ago, that all the characters who have war ties, I imagine from Red Skull to Magneto to original Nick Fury and so on, will have been part of.
It's an interesting creative move, but I think very stupid, especially for characters from the Second World War like Magneto. What makes him such an interesting villain and sympathetic character who you can see changing sides like he has repeatedly is that he has a deep, personal connection to the attempts to wipe out an entire race, and that informs how he sees mutants versus humanity. The analogy just doesn't work as well with any other group or time period in the last century of history, so trying to change it to the struggles of African Americans in the 60s isn't nearly the same as genocide.
Who'd have thought, Waid would be involved in a story-telling decision that sounds like it solves some problems while actually deeply damaging legacy characters...
