The human rights violations that ICE commits should not be considered a political matter regardless of whether one party endorses them. Supporting those that enable atrocities is not politics, it's publicly announcing that you are a defect of evolution.

However, ICE will do what they are told and allowed to do and I don't see how this makes any difference. If they're forced off GitHub, they'll just take more taxpayer money to migrate to another platform because those above them in the hierarchy support what they're doing. The anger toward ICE is valid, but just like in medicine, treating a symptom does nothing toward treating the root cause.
