BSD lives on today through FreeBSD, NetBSD, and OpenBSD. NeXTStep was also based on the original BSD, Apple’s Mac OS X was based on NeXTStep, and iOS was based on Mac OS X. Unix was not open source software, and the Unix source code was licensable via agreements with its owner, AT&T. The first known software license was sold to the University of Illinois in 1975. Unix grew quickly in academia, with Berkeley becoming a significant center of activity, given Ken Thompson's sabbatical there in the '70s. Technically, it isn't. It's just that it's totally dead after being eaten alive by Linux and BSD (which started as patches for Unix). It's just that open source & free software can better compete against Microsoft than way too expensive arcane software like Unix was!

Today, open source is an idea that nearly everyone knows. Around 64% of current servers are UNIX or UNIX-like in design. Only about 36% of the market is dominated by Windows. UNIX has recently fallen out of vogue for UNIX-like servers. Over half of most developers use open source Open-source definition: Refers to both open-source software and hardware, and connotes a set of guiding principles with an emphasis on transparency, collaboration, community-centered development, and open exchange. Source code or files are freely available to view, modify, and share.

I don't know the answer to that question. But I have rounded up some theories, which I'd like to lay out here. Open source, social movement, begun by computer programmers, that rejects secrecy and centralized control of creative work in favour of decentralization, transparency, and unrestricted (“open”) sharing of information.
