I get your point, I do. Then again, a lot can be said about the "PR value" of letting what could be miniscule (by comparison) costs of serving static hypertext, be saved in the eyes of "potential" customers. It's pennies on the dollar and I am fairly sure Microsoft would get a lot more love from the "neckbeards" who need the old-school stuff and not the toys they insist on dangling in front of our faces (which they are famous for). Remember when Microsoft tried to get everyone away from Win32 by force-feeding everyone WinRT, writing "deprecated" over the former everywhere they could on their site(s), only to witness such a shit-storm of complaint and fury from people who actually rightfully knew Win32 was, for all its faults, one of the better things Microsoft has given us (in context of Windows programming, that is)?

Speaking of Win32 but not only that, I too have started being more cautious and pedantic about user manuals and other "paraphernalia" I have to rely on, for instance Win32 API documentation which is getting more scarce to find in sufficient volume and specifically _detail_. So I download and archive it (with implied off-site backup, which I have for most of my "home directory" stuff) -- I agree the only way to guarantee access is to, well, obtain a copy of the document...
