It was a weird time last December: After the cancellation of the congress was announced, there was a large congress of intensive care workers in Germany where the attendees were going around mostly maskless. I mean, who would be better at estimating the risks?
I also don't understand why the German hacker scene was and still is so much in favor Covid restrictions. There are hackerspaces that still require N95 masks today while in the general population nobody cares anymore. I honestly think that it's mostly virtue signalling, i.e. showing that you're a good member of the scene.
