I Don’t Understand the Wayfair Walkout

Somebody help me out here. This is a genuine question, not snark.
Wayfair, the online furniture giant, has apparently been selling beds to the government for use in immigrant detention centers. Its employees are unhappy about this and they want Wayfair to stop sales to ICE or CBP or any other agency involved with keeping kids in cages. Wayfair’s management has not agreed to this, so today its employees staged a walkout.
But isn’t our whole complaint that these kids are being treated badly? Shouldn’t we want companies to sell the government toothpaste and soap and beds and so forth? What am I missing here?
