In computing, cooperation includes redistributing exact copies of a program to other users. It also includes distributing your changed versions to them. Free software encourages these forms of cooperation, while proprietary software forbids them. It forbids redistribution of copies, and by denying users the source code, it blocks them from making changes. SaaSS has the same effects: if your computing is done over the web in someone else's server, by someone else's copy of a program, you can't see it or touch the software that does your computing, so you can't redistribute it or change it.
