Only "OCTA OS" is Open source, and that could be because its tied to its own Assembler ?, (so hard to rip the code ).
That says to me that open source does not work, as at one time all these OS's have all been Open source or in DexOS's case, not open source, but source available. Now why does opensource not work ?, that's because it is slavery

They sell you this illusion, that your working for the good of mankind, bull s**t, your working for nothing, that's slavery.
Big Co can now get what they use to pay top $ for free, at the same time the general public pay M$ and apple lots of $$, and do not want to know Opensource, until they need to crack this protection or download peer to peer etc.
Why do we not ask plumbers, joiners, motor mechanics, school teachers etc to work for free.
I think all Open source coders should go on strike, as the world could not run without computer.
