Do you have any source for this (that isn't just rampant speculation)? If these things are going on and actually impacting editorial work within Wikipedia itself, it sounds like we are due for a nice little Wikipediagate...
Also, what is your take on this? Why do you think the foundation, that usually only steps in when someone is posting something highly illegal like child porn etc., bypassed the orb committee this time? Why is the complaint being shrouded in secrecy?
There's definitely something funny going on, and this is the only line of reasoning that makes sense to me. But I'm open to other ideas.
I've seen no explanation in the article or in any of the discussion which would justify keeping the arbcom in the dark here. It's quite surprising, but not the first recent incident of WMF doing this.
