#FOSDEM is basically admitting they're a super spreader event.
There are many science-based things conferences can do. The Public Health Pledge (@phpledge) has badging principles with suggestions on how to help prevent people getting sick (at different levels, in various ways): https://phpledge.com/badging — but FOSDEM isn't doing these things. They could.
(Many of us attending in-person got FOSDEM flu in years past. But now COVID is in the mix)
Hoping that everyone stays well despite this. 🍀
