Personally I wouldn't want to work for a company actually detaining people, but call me terrible but I'm not sure I'd feel the same about letting them pay to host some code...
However, would you be ok with Hitler hosting code on your service if it contributed in some small way to genocide? That _does_ make me feel ick. Tacit support by large numbers of "not really effected" people is what made the holocaust and slavery and jim crow, etc, possible.
I'm not comparing ICE to Violent White Supremacy... but it's worth staying informed and revisiting our own boundaries as the situation changes.
Skin color, nationality and ethnicity are playing a huge role in how we're treating people right now, and the spectrum of human<>inhumane is getting wider and wider with tacit support :-(
