@Ashok, the only reason that you and others use linux/unix kernel for "free" is because of the hard work of student activists and the hacker activist communities in the early 90's that were anti- corporate. Keep in mind that the student and hacker activists have a roof over their heads because their govts provide the infrastructure, make enough money to pay for bills etc. However, it seems the concept of free software to open software is big business too. Some of the funds and grants contributors may also be DOD funded programs, the same DOD that produces weapons and technologies that kill worldwide. Other fundings could well be from unknown sources, including donations that are looking for tax exemptions. The example of this is the issues between Ubuntu and Mint. Why the Ubuntu founder and financier does not think about creating *free energy for South Africa* is baffling. Energy costs that are driving poverty further. I also don't see the concept of Open Hardware that will be available for free thus reducing the poverty gaps. I only see economic mischief in the so called open source/free software that the final frontier i.e Africa is trying so hard to embrace. Nothing is free. Corrections welcome. :-) Rgds.
