Harder how? Explain how making ICEs deployment pipeline slower will make ICE release migrants or stop family separation.

If you want to claim that Chef should cease business with ICE explicitly on the moral grounds that no company should have any business with the agency, that is a valid claim. But to say that Chef had any influence, let alone "all the ability" as the root commenter wrote, to affect ICE's conduct is not a statement I find to be honest.
