> anyone could fork a program and release an identical, competing version of it. And still, all of the developers I interviewed considered the right to fork to be a cornerstone of open source software.
I have two problems with this article (and probably thesis).
First you can not just fork and release identical version of program. Most licenses require to use different project name, clear author identification and so on. If you fork and release Firefox with some spyware, you probably get sued by Mozilla.
And secondly forking is not 'right'. Rights have to be codified, are guaranteed by someone and can be taken away. Ability to create fork is just something which is not forbidden.
