I feel like you're looking a bit too much into it and that this rant is a bit unnecessary. You write as though you're being attacked by the creators or something. It's not going to "replace your MacOS" or anything, but rather is a showcase of clean UI and UX. Looking through the "What" and "Why" sections on their Github says how it follows certain UI and UX guidelines; many of which Apple has adopted. I don't think you're the target audience either. If you're interested in FreeBSD and like MacOS, you'd probably love this.
