If you have not watched the video, trabant00’s comment will sound somewhat odd. However, the presenter does indeed draw parallels between C and Colonialism around 17:25 into the video, the part about macOS is at roughly 25:30, and the “straight white men” part at around 30:25. Without this context I do think it is difficult to understand why trabant00 wrote what they wrote, especially as the video very much starts out on a much more technical note.
