It doesn't really say what parts of the MacOS philosophy it's aligned with. Seems more like riding on coattails. What is listed are a number of differences that apply to most any Linux/BSD distro. I think 'philosophy' here means surface appearance of the desktop.

And if it's about openness, why link to the branding pages rather than the source repo? I couldn't even find a link searching for 'source' on the page.
