"Hackerspaces tend to be (...) spaces that tend to overlook fire, health/safety, and disability building compliance."
I think that's not very relevant to this specific occasion, because the fire did not start at the hackerspace. The first flames and smoke were on the opposite side of the huge open warehouse, of which the hackerspace was just a relatively tiny part.
Pixelbar was a small free standing two-storey building within the very large warehouse. I don't know if the hackerspace was built to code, but I think it wouldn't have mattered much in this case. By the time the fire reached that building-within-a-building, it must have already been a nigh unstoppable inferno. The fire safety of the surrounding warehouse may have been questionable, but you can't really blame the the hackerspace for that.
I hope that people who host forums, image boards, chat applications, etc., will delete or fix potentially vulnerable images before anyone uses them maliciously.
One way to repair a vulnerable image is to use `optipng -fix`.
I think the logo is cute though, so let's keep it. I think it was made with the WHY2025 logo generator at https://design.why2025.org/
