It's a poorly translated word written in a haste. A better translation would be "red neck" (I think?). This is translated from my inner Swedish thoughts and we don't have Californian wokeness here (especially not down here in Skåne). But instead of finding a new word I reformulated that section everyone is so upset about. It's fascinating how easy it is for internet people to assume worst intent in everything, and look for things to be offended by, rather than to read between the lines and adjust ones interpretation based on context.
If you read the section, applying context from what the project is about and where it is used, you should pretty easily grasp the overall idea that is: "compression sucks and is incredibly inefficient". It would be a much more interesting thread if people took that message and argued against/for it, technically. But now we are here arguing about some word usage that might be offensive if interpreted in a very literal way. Congratulations; we have reached peak cancel culture. I hope you enjoy it while it lasts.
