Whoop-de-do. If you don't like the company, leave.
If all the employees with morals leave, GitHub will be left with no employees with morals. That is probably a worse situation.
I'm mean you don't invite people to your well build house who don't even know how to use the toilet right. So be harsh but fair on immigration and only allow the people who can contribute to a better society.
The same as in their github environment. They don't allow people to work within Microsoft who are just fired at Burger king but don't have any relevant capabilities right
