I'm sympathetic with those who point out that corporations typically have more leverage than individual employees, and that changing jobs is not so easy for those who are less privileged. That category, though, of "less privileged" with regards to employment flexibility simply does not apply to the average Github employee, at all, as sircmpwn frequently points out.
Furthermore, regardless of which side of this debate you stand on, it is definitely disheartening to see people so vehemently against this relationship yet do NOT back up their feelings with actions. I cannot help but scoff when I see people on Github with "stop ICE" profile pictures. It's nothing but a profound selfishness: wanting to be on the self-perceived "right side of history" but not so much so that you set your origin to Gitlab or SourceHut instead...
