At motorola support forum there was a thread started by someone asking for motorola to just "leak" the keys... suddenly a hex code sequence appeared at the forum and the thread was blocked (requires authorized access). Now, there is a really HIGH probability (like 99.99999999%) that this is just a joke... but who knows... here what was posted:
Almost forgot about this thread! So anyway, here is that key you asked for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
Ok, it is a joke, it's an encoded string, here is the text:
Greetings, fellows. We know that you are dying for the unlocked bootloader. Moto is not the only "player" that has an influence over decision - carriers have their say in it too, so don't just blame us - contact the carriers too. As a fellow engineer - my personal opinion is to not limit knowledgeable users by locked bootloader. But I also? think that modding of the system sw voids the warranty - would you be willing to void a warranty by unlocking and modding the phone? Anyway, this is meant as a tongue-in-cheek little joke, not something to be taken seriously or to have conclusions drawn from it, nor is it in anyway representative of an official company view. Have fun!
