Why are yall so mad about GNU and Free Software movement that it has started? Do you prefer to go to the old times? Apple microsoft fanboys?
Doing an entire OS and library to not use GNU it's like Apple doing the LLVM to not having to use the GCC. Instead you could be helping in the free software movement and development, but you prefer to go into a GNU vs. Linux fight.
The war should be all the free software movement vs the companies fake open source shit.
Un*x. All those projects hate Unix because AT&T started the sue against BSD that broke apart the status quo of open software at that time. Since then all free software is not unix. All of them are POSIX tho.
