I feel like it may be the other way around? If GitHub was the exclusive provider of some important service - like a utility - I would feel strongly that they should continue to offer the service despite political differences (even if not strictly classified as a utility). On the other hand, since there are plenty of alternatives, there's no huge & lasting damage that could result from Github choosing not to have a particular customer - and as such they should have more freedom to deny any particular customer. As such, I think it's should be fine, ethically speaking, to discontinue a professional relationship with ICE should Github management decide that continuing a relationship with ICE is counter to their values or something, in which case the devs do have a case they can try to make (that ICE is counter to their values).
