To me it sounds like you made a decision to drop your holdings based on conscience. But I question how your conscience was troubled by the supply of services by DXN to this facility.

The "concentration camp" you are referring to was the quarantine facility intended to immediately serve for isolating visitors to Australia during the COVID-19 pandemic, and to remain longer term as "for other important uses such as supporting responses to natural disasters or other emergencies."

That doesn't sound like a completely bad thing to me. Did you object to the quarantine of overseas arrivals during the pandemic? Would you rather have no quarantine?

If DXN didn't supply services to the facility, some other company would have gladly raised their hand - possibly - perhaps likely - an overseas supplier - would you have preferred that outcome?
