Your statements are "facts" only by technical definition; that is, they convey information that can be verified as true or false objectively. They are not facts in the common-usage definition, which generally refers to objective statements known to be true.
To turn your assertion into something that is objectively known to be true, you would have to say something like: "Apple does not support use of more than 8GB of RAM in the 15" and 17" models, and cannot officially assist you in any way in attempting to use more than that." There is anecdotal evidence in this thread that somebody has been able to make such a configuration work at least partially on at least one occasion, which, if true, means that "[these models] accept a maximum of 8GB" is, as a blanket statement, verifiably false.
Besides, if you read back through the entire thread, you can see that we figured this out (that Apple doesn't support more than 8GB in these machines) several pages ago. So pointing it out again, 19 pages into the thread, doesn't add anything productive to the conversation.
Furthermore, as an apparent Level 8 member of this forum, you ought to know without having to even think about it that Apple has not made a 17" MBP since they discontinued the 2011 model (the MBP8,3), so those of us who need that size of screen and more than 8GB of RAM have no options currently available from Apple at all, and the only existing solution that doesn't involve some kind of hack is to find a MBP8,3 for sale in good condition somewhere—and good luck finding one at anything resembling a reasonable price for a model that's three years out of date.
Apple has given no indication that they ever again intend to make a 17" MBP, Retina or not. So those of us who need it have to make do with what we can hack out of the ones we already have. And that's what this thread is ultimately all about. All that your comments have done is reveal that you believe that making a comment, even a counterproductive one, is a better use of your time than ignoring a thread that you have nothing of value to add to.

Now, if you'll excuse the rest of us, we'd like to keep trying to find a solution. Go rain on somebody else's parade.
