On Friday, LA president Hugh Blemings issued a statement on the group's main mailing list, saying that Appelbaum would not be invited to the next Australian national Linux conference (LCA 2017) or to the next event on LA's calendar, its annual Python conference which is known as PyCon Australia.
On 22 June, Blemings had issued a statement saying that the organisation would not place any restrictions on Appelbaum's potential participation in any of its events until "facts in this matter become clear".
Exactly what prompted this volte face in the space of nine days is unknown. There have been no disclosures about Appelbaum in the last few days that could logically account for this change in LA's stance.
In the statement announcing the change of policy, Blemings wrote that the earlier statement (on 22 June) "did not communicate our position effectively, and in some cases resulted in our commitment to safety at events being called into question. We apologise for creating this perception. This statement seeks to address that".
He said that the organisers of the LCA 2017 and PyCon had taken the decision to ban Appelbaum, based on reports on "various sources making and supporting the allegations" against Appelbaum.
