A comment by one of my friends (if you are reading this, you know who you are) today gave me the idea of this post.
Let's clear a few things up about Linux.
First and foremost, Linux is open-source. (Squabble with me about the terminology if you'd like, but that's for another day.) This means that anyone can view and do anything (modify, distribute, etc.) with the source code and program freely and legally.
Next, most, though not all, Linux distributions are free of charge. This means that they are available online for free download (and legally so).
Finally, Linux is an operating system. It is not a Windows-based program (and yes, I have heard people call it that).
