In the future, after the Microsoft Corporation schemes and bribes its way to become the puppet master to the United States Government starting with the Obama administration, Linux and all variants get listed as terrorist organisations and development is forced underground.
Development bases and fortresses are formed in inhospitable areas of the planet such as kilometres under the sea in geodesic dome cities, small at first then growing ever larger, not without some accidents during initial construction. Other rebel bases are formed in the Antarctic using renewable energy and remote radio transmitter stations. Bandwidth at the most remote locations is terrible, these are the bad times.
Microsoft eventually permeates every level of the Old Unites States government via bribes and manipulation of an ignorant public, restructuring government based on economic self-interest and to fortify and defend the core corporation. There is no public uprising or outcry from the members of the mega cities as they are afraid that they will lose the licenses on their windows installations that are now the core of everyday life for an urban citizen. The mega farms are all remotely controlled by heavy machinery running Windows Tractor Edition and other variants. When a citizen has the new “Universal Microsoft License” revoked, that citizen is prevented by the harsh rule of law from benefiting from anything directly or indirectly generated or assisted by Microsoft software or related technology as doing so would violate new ironclad copyright law.
