Trump is playing to his political base....
But as for Github and its contracts with U.S. Immigration and Customs Enforcement (ICE), there is a difference between working for a government arm that encharged with enforcing a country's immigration laws, and working for some organization whose stated policy is "immigrants out!" and "America/Europe/Australia for Americans/Europeans/Australians!" You can certainly debate that the immigration laws are too harsh or too lenient, but they are laws that have been passed by the governments and representative bodies concerned, and then are regularly examined by courts to make sure that people ensnared by those laws are given due process.
For example, I bet Github has contracts with lots of European defense ministries, navies, coast guards and border police organizations that are instrumental in turning back migrants trying to get into Europe across the Mediterranean and Aegean seas.
