We always ensure that we don't use even "less-known" proprietary software (forget M$ Windows) in smaller GLUG level events, workshops or presentations. But an International event on Free Software showcasing proprietary software is, bad.
:( Cannot show my face now to all our student activists here.. What you said is true.. in the phase of engineering colleges turning to GNU.. students of the respective colleges taking care of their labs.. we might be having a tough time.. once we go into people... and they ask.... " Is it true that free software can't do with out prop..?" I pray GOD this doesn't happen.... :(
AND MORE IMPORTANTLY THIS IS AN INSULT TO RMS.... THIS IS AN INSULT TO FREE SOFTWARE MOVEMENT.... we always showed alternatives and better software to people stuck up with proprietary software.. but WE DON"T FIND ONE FOR OURSELVES ???? that too in an international conference ( questioning the movement in India at a global scale )..... UNACCEPTABLE...
