clckwrkwhich is just someone getting mad at epidemiology
If this was in 2020, I would wholly support canceling this event to slow the spread. But now, the vaccine exists, and it means events that require vaccinations or a negative test have very low infection rates, around .05% in the case of Lollapalooza, which saw crowds over 100k daily, with masks not being universally used. It was outdoors though. I guess for some, 2-3 infections for a tf2 lan is an unacceptable risk, but it is evident that for most people, the risk is minimal enough to justify, as is the case for multiple in-person CS:GO majors, or Smash tournaments with well over a thousand entrants.
