Dude is against open source cuz "it mathematically leads to monopoly" while working for Microsoft.

capitalism leads to monpoly. not open source. why does capitalism lead to monopoly? because capitalism is competitive, and competitions have winners and losers. when a loser enterprise is vanquished under capitalism, it is either driven from the market through bankruptcy, or it is absorbed/merged into a winner enterprise. Eventually the winner enterprises get so big that it is prohibitively expensive to enter the market in competition with them, and smaller firms simply become auxiliary forces for the large firms, to be absorbed when the charade of separateness is no longer useful. Once all firms are vanquished/absorbed/made into auxiliaries, you have a vertically and horizontally integrated monopoly enterprise. How do you get rid of this monopoly? Under socialism, you would nationalize it. Under capitalism, you simply "trust bust" it like Teddy Roosevelt did, and force a RETVRN to the state of competition. In both situation, will complain that you are "punishing winners", of course.

"Single payer economies leads to bad things like Bolshevism and Stalin"

Even if you think Communism is bad, this is idiotic. Single payer policies alone aren't socialism. If an imperialist capitalist state has free health care, Lenin is not going to rise from the grave. And Tsarist Russia, on the eve of the October Revolution did not have a "Single Payer Economy" which led to Bolshevism lmfao.

What led to Bolshevism was the failures of the Tsar and his ministers, the Russo-Japanese War, WW1, the black hundreds, the pogroms, the failure of the 3 dumas, the failure of Stolypin's reforms, the failure of the provisional government and Kerensky, etc. etc. etc. shit this bazinga brain has probably never even read about.
