Probably a mix up of sorts and the responsibility lies with the contractor that installed it. I don't believe the Bored Apes crew organized everything themselves down to the lights, it's not their job. They just paid a company to do it for them.

Asia is much, much more serious than the West regarding sanitation, especially since COVID. UV door frames at the entrance of public transportation is a thing. Where I live, before entering a pharmacy during COVID I had to step in a pond of sanitizer, then was sprayed with the same, then had to wash my hands.

I'm not surprised the contractor had a stockpile of UV tubes to be used specifically for sanitation purpose. Now, did they just confused them with regular black light tubes or did they use them on purpose, or a mix of the two? I guess there's going to be an investigation to sort that out. Wouldn't like to be them, the Hong Kong judicial system is not known for being lenient, quite the opposite.
