big impact- Open-source vs proprietary
Proprietary software is licensed, not sold, with severe accompanying restrictions on copying or modification.
This scheme was not devised by fools. It reduces piracy, rewards risk, and allows vendors to enforce compatibility
. And when a proprietary vendor controls industry standards, it generates fantastic amounts of money; Microsoft alone has created about 10,000 millionaires through employee stock options.
And yet there are now literally thousands of open-source development efforts like OpenOffice, Firefox, Linux and Apache that have been downloaded tens of millions of times. Why?
