I bet you use DNS, TCP/IP, browsers, etc for your application to run over a network.

The application was perhaps written in c/c++ as well--compilers are open source.

If your application is internet-aware or -capable, then it relies heavily on open source software.

Do you use putty for any connections? FOSS.

SSH? FOSS.

My point is that you can't get away from it. It's all around, and you rely on it quite a bit more than you may know.
