It's good PR CYA. They ensure that there will be a much lower chance of an article headlined "mass shooting at rust conference" being written.
I am personal'y of the opinion that brands play it too safe in general and people aren't stupid and know that just because a brand happened to be near something bad doesn't mean the brand is responsible and therefore bad, but apparently brands don't agree and they're the ones calling the shots on where they're displayed.

I don't think this follows. Historically speaking, most mass shootings have occurred at locations that specifically disallow firearms, making them "soft targets" where the cowardly attacker will not have anyone fight back. It doesn't seem logically consistent to assume that this policy item has the effect you are stating.
