Someone just told me that Jack's networth is nobody's business at #FOSDEM.
I disagree: there's no ethical/moral way to become a billionaire, much less remain one.
Commercial events might get away with defining "politics" as "out of scope" (ignoring the fact that that in itself is a political stance, and not a great one), but a truly public community event has to cope.
Plus, decisions by event organizers absolutely are subject to scrutiny.
