How software was sold
Jacquard’s Loom 1801
The Analytical Engine
hollerith
Generation 3 (1964-72)
Selling/Leasing hardware
1969 
IBM began to charge separately for 
(mainframe) software and services, and 
ceased to supply source code.
Copyright & Copyleft
"technical means to 
a social end." Stallman
Starting this Thanksgiving I am going to write a 
complete Unix-compatible software system called 
GNU (for Gnu's Not Unix), and give it away free to 
everyone who can use it. Contributions of time, 
money, programs and equipment are greatly 
needed. 
Stallman (1984)
Philosophy
The freedom to run the program as you wish, for any 
purpose (freedom 0). 
The freedom to study how the program works, and change 
it so it does your computing as you wish (freedom 1). 
Access to the source code is a precondition for this. 
The freedom to redistribute copies so you can help your 
neighbor (freedom 2). 
The freedom to distribute copies of your modified versions 
to others (freedom 3).
“Free software is a matter of liberty, not price. To 
understand the concept, you should think of free as in free 
speech, not as in free beer.” Stallman
GNU General Public License
GNU is not in the public domain. 
Everyone will be permitted to modify 
and redistribute GNU, but no distributor 
will be allowed to restrict its further 
redistribution. That is to say, proprietary 
modifications will not be allowed. I want 
to make sure that all versions of GNU 
remain free. 
GNU Manifesto (1985)

Copyleft
Open Source
The term “open source” software is used by some people to 
mean more or less the same category as free software. It is 
not exactly the same class of software: they accept some 
licences that we consider too restrictive…
Return of Selling hardware
Tivoization is the creation of a system that 
incorporates software under the terms of a 
copyleft software license (like the GPL), but 
uses hardware restrictions to prevent users 
from running modified versions of the 
software on that hardware.

  • #8 Sheep standing in the cold from P!XELTREE cc by nc sa Until the late 1960s computers—huge and expensive mainframe machines in specially air-conditioned computer rooms—were usually supplied on a lease rather than purchase basis.[6][7] Service and all software available were usually supplied by manufacturers without separate charge until 1969. Software source code was usually provided. Users who developed software often made it available, without charge. Customers who purchased expensive mainframe hardware did not pay separately for software. http://en.wikipedia.org/wiki/Proprietary_software
