Interesting. I have never received a Linux system with either the
source code or a written offer of source code. I certainly know where
to download it.

Presumably we could have included a CD, regardless of whether
recipients had drives.

Wouldn't surprise me. Who is supposed to take care of this stuff?

OK, now I know what you are talking about. Yes, I would prefer
children to have complete software freedom. I don't see it happening.
I expect that if faced with this question directly, governments would
uniformly assert that they are the consumers, and that no court in
their countries would disagree, since the government paid for the
equipment. I also see no way that a US court would hold any of this to
be a license violation, given that the source code is delivered to the
governments.
