As I wrote, we just published their event without permission (as any other event). There were lots of events taking place in Prague that week, and we just compiled an overview.
They framed our neutral infrastructure (an event aggregator) as "parasitizing" and "damaging speakers" when we were just doing what event aggregators do - providing information about what's happening in the city. Classic example of institutionalists treating neutral tools as threats when they can't control the narrative.
