Ah that's an interesting point. TCP/IP is a standard, so it's non free...
No, that's not true. The idea of TCP/IP is free --- an idea can't be covered by copyright, and there is AFAIK no patent being actively enforced on it. A particular description of the idea of TCP/IP could be non-free, but that doesn't make another description of the idea (the source code in the kernel) non-free.
And, actually, most of IP and TCP are from earlier RFCs, which (if I remember correctly) are free...
