Ubuntu and Debian are NO longer GNU even though they make the claim. Here are the free GNU operating systems and remember free has a GNU definition that The Silencer Project Companion Book examines like NEVER Before and NEVER AGAIN. Ubuntu represents the commutative efforts of the Linux Community that Microsoft stole from the free world like government pays for things leaving the payee WITHOUT any choice in the matter like the Koreshan Settlers of what is today called Koreshan State Park. Like my grandfather's paid slave labor that produced the IRON Ore that Japan enjoys or my grandfather's trailer park that government seized by unjust and unconstitutional eminent domain and so on and so forth. Microsoft opened their code for a short time ONLY to deceive and get what they wanted to then close their code door forever and ever. Their acquisition (theft) of Ubuntu gives them the best of both worlds. The two worlds that others built. Microsoft, ® as all government, corporatism, communism are criminals and need to go, Get rid of them all by choosing FREEDOM.
