Free and Open Source Software

OK, since this was my first post here I did not expect the conversation to get so lively. I appreciate every single input. I thought my initial request was simple and clear with the words "non-tech" and "family members" but for the curious I will expand a bit.

For starters of course I am the "sys-admin" of my families tech life, my main personal PC is not Windows based but every member of my family is because every flavor of Linux I have convinced a family member to try has resulted in utter failure for them, sad but true.

They like the simple UI over the Windows firewall because I had no success trying to get them to understand/use the built-in windows version "Easy" to block per-process out/in traffic "Easy" to block ALL traffic, etc... Having them understand/use traffic blocking at the app level has made all of them much safer/smarter users. I start them with almost everything locked down, they open/monitor what they use, nobody shares a PC so this works perfect.

and finally for me, I needed Open Source so I can inspect the code for any tomfoolery, make any custom changes needed/wanted, and compile on my own. Free is never a requirement, I will always support the devs of software I end up using.

Thanks again for all the input, I read and followed everything, I was not planning on this much TMI but felt it warranted after reading the responses.
