For me open source is a simple matter of practicality. Open source software is freely audit-able and usually free of any kind of trust issue. If something is not open source I simply don't install it on my computer because I must assume the author is trying to hide something. So far this has protected me from the Sony rootkit fiasco and the Sprint/Samsung IQAgent keylogger debacle. All closed source software I use is provide by my workplace on a machine they provide. Or the low level radio driver in my phone :( . OR is installed on a special untrusted machine dedicated to such use.
