No they're not, since they were being used to claim Red Hawk wasn't being distributed, when the thread was a press release announcing it LOL! Yet here you are, months later, still lying.
No, both statements were and in context. The first one refuted your statement-as-a-question claim that "Don't they have to give a copy to anyone who wants a copy?" No, they don't.
The second one was in response to your claim that ""I was pointing out that anyone in the world could get a "legal" copy of that source code once any single customer decides off the cuff to release it," Your modifications to Linux may be GPL, but you can claim the the code as a trade secret, releasing it only to your clients (IAW the GPL), the ones you have distributed it to, the ones who have signed an NDA. This is a contract on top of a license. Thus if one of your clients releases the code, you are not without legal recourse to get compensated for any damages that may have occured.
For actual modifications to the code of others, the same basic concept exists with the Mozilla and Sun licenses.
