Saying “everyone knows these products are backdoored” and then supporting your claim with “well, they’re closed source” is a ridiculous thing to do. Please stop.
Please stop? I just cited two credible sources on either side of the backdoor. It's one thing if you don't want to acknowledge what's happening, it's another thing to publicly deny it. If you've got any concrete evidence that Apple does not furnish backdoors in their products, now is a good time to show it. Otherwise I see no rational reason for anyone to assume Apple products are totally secure.
