This is the second time I remember that the Friendly Space Policy was invoked to remove a Wikimania attendee from a situation, presumably because of in-person misconduct on their part, where the removal was made public but the reason of removal was kept secret.
The problem with such secretive invocations of Friendly Space is that it is very difficult, as Reem and others have pointed out, to not see this as a punishment.
I understand that it is very difficult to balance the specific, personal sensitivities and cultural preferences of several hundred people from different cultures. But as this discussion has shown, it is counter-productive to use Friendly Space this way, because other Wikimaniacs are left worrying what the appropriate behaviour is supposed to be.
I don't know the details of this incident because it wasn't public. But from what I know of Romaine from previous Wikimanias, I'm disappointed that this incident couldn't have been handled behind the scenes with T&S and the people involved. The fact that Romaine felt the need to go public about his removal as an organiser showed mis-handling of process.
Well, actually the previous time was 6 years ago, so maybe we're doing well. We did try reforming the friendly space policy around 2013-14 but couldn't agree on something better at the time... The doors of improvement always stay open for the Wikimedia movement.
