I think just making a Linux distribution that mimics OS/2-like functionality...
I have not worked with Linux or GNU for matters of conscience. When I look at Linux I see Linus Torvalds, who is by all accounts a vile, crass, mean, spiteful, insulting, profane individual who thinks nothing of giving people the finger on camera, or using all manner of profane words to yell at people online. And when I look at GNU I see Richard Stallman, who is by all accounts, a complete pervert who believes that pedophilia and necrophilia should be legalized, among many other odd things.
I had planned in 2012 to go to GNU and complete the GNU HURD kernel for them, but then I learned those things about Stallman. I had already decided not to work on Linux, which is why I was moving toward the HURD kernel.
I'm sorry, but I cannot support Linux or GNU for those reasons. It's why I'm creating everything from scratch. I want to have an offering based on holiness, on a real giving unto God purposefully, and not just creation for the sake of creation, and not for money, not for fame, but to honestly give the world something wonderful they can use, and without the negative aspects of mankind associated with existing offerings apart from forgiveness and repentance through Christ.
My intention with ES/2 is to give people the best we can create, and to do so to empower them. Full source code. Full legal rights. Full everything.
