It's great to see optimism on here, especially about people's personal open source projects! Cynicism is appropriate when talking about commercial and larger projects and news, but for people doing things for fun and in the open, I'd always choose the most charitable and uplifting thing to say.

About the content of your comment : IMO a true Linux replacement would also need to be gpl or otherwise strongly copyleft licensed. The fact that gpl has forced some corporations into co-operation who otherwise wouldn't have is worth a lot!
