I agree that it would be better to have the source code for things. However, what good is the source code if you don't know how to, or even worse, can't build it because it was always built using an intricate web of build systems that rely on servers that no longer exist? Can I patch and recompile the project on my computer and is it easy to find out how to do it? Do I even have the tools to build it freely available? Unfortunately, a great many open source projects fail this test.
