Sure they can. Anyone (who is in posession of a legal copy) can USE any computer program for
any purpose, you don't need a license for that.

Now, if they want to DISTRIBUTE the program they -do- need permission from the
copyright-holder(s). For a GPLd program, one way of getting that permission would be to comply
with the GPL.

Another way would be to contact the copyright-holders and negotiate alternative arrangements.
In the case of the Linux kernel though, that is practically impossible since there are so many
distinct copyright-holders, and you'd need to negotiate a deal with every one of them, many of
which have no interest in such a deal.

Who is in posession of a legal copy? How?

Sure - if you do in fact have legal copy you can use that. But if license is null and void then surely you don't have a legal copy!

err-ata

Er... my bad, meant "embed and sell" (that is "distribute") as "use".  Should have been
sleeping for good %)

The license doesn't at all enter into the question of if you've got a legal copy or not.

If you go to www.kernel.org and download a copy of the linux kernel, this is a legal copy of
Linux. It is because www.kernel.org does infact have permission to distribute it to you (they
have this permission because THEY follow the rules stipulated in the GPL)

Now you are free to use this single copy of Linux any way you want without even READING the
GPL, much less adhere to it. It does in no way matter if you've got a license or not, you
don't NEED one.

The moment you want to do something that is otherwise prohibited by copyright-law, such as
distributing copies of the kernel to others, THEN you need a permission -- which the attached
GPL will give you on certain conditions. But only then. If you do -NOT- plan to distribute,
say you're only planning to use Linux on your own computer, then the GPL does not restrict you
in any way. (it even says so in the GPL, but even if it didn't, this would be the case)

I really don't understand why people persist in thinking they need a LICENCE to do something
that is allowed by default.

You only need a licence if you want to do something that is FORBIDDEN by default. (such as
distributing and copying the creative work of someone else)
