What was shared was a leaked chat transcript demonstrating the coordinated efforts of many working to silence support for Palestinian liberation.
The transcript clearly demonstrates collective actions taken to contact employers, funding bodies, publishers and journalists to censure anyone deemed to be a threat to zionist ideology. Some of these efforts were successful, the firing of Antoinette Lattouf being but one example.
Basically, they were running harassment campaigns out of a chat that used real names and someone leaked it.
