Linkedin doesn't put children in cages, to the best of my knowledge. (I just randomly chose one company from the list).
This list is random. There are companies which do business with federal government, some of them with ICE and law enforcement agencies. I'm paying federal income tax in the US and as every other citizen or LPR or even H1B visa holder fund ICE. I'm much more complicit in "putting children in cages" than Linkedin.
