Heck it is cheap.
Year’s back Chinese government thought it is too risky to use closed source software like Microsoft’s product in government and military institute. Sure they want to make sure what’s the heck is going inside Microsoft’s software. For that reason, Microsoft concedes its source to Chinese government, as China is a big market. The same reason US military, intelligence and other sensitive institute favors open source, they too want to make sure their software do exactly what it …
…suppose to do.
Once market saturates with proprietary software and open source can do any thing that closed source do or may be more. Once consumers (particularly in US) try to find software that save some money, then open source going to play a big role. Investing some resource/time/energy now on open source is really good idea and is very good future investment.
