All open source projects are not the same. All the people running open source projects are not swayed by money. Some projects are much more complicated than a web framework. These projects need funds for progress to be made. Case in point - OpenBSD. I love the project and their approach. I also feel they genuinely need funding to keep improving the system. Another example - LuaJIT. Great project, does not have a load of contributors - so I won't mind funding Mike if it means he spends more time on LuaJIT. Another example - SQLite. I'll just send in a donation because its so damn good.
