That's not unique to acronyms though. It's entirely possible to be arrogant while pretending to care about the other party in a fully-fledged sentence. Just like with any other form of speech, acronyms can be used for good or bad.
Heck, one of the last times I spoke with my mather, she followed the usual "how to make sure the other side feels cared abut"-advice to the letter. Meaning she followed the form and form only.
I'm trying to make the link between your subject line and the actual message content.
If you're looking for API references, the online docs are probably still your best bet - at this point even the very last MSDN disc that got pressed is now horribly out of date. I've sent the few thousands I still had for recycling a few years ago.
Nobody wanted the discs when the company I worked for was acquired by a bigger fish and our local office subsequently got shut down. That was back when MS made everything available on CD/DVD, including all available languages.
Like you, I've kept the various binder types they came up with over the years--they're still useful. I also kept a small subset of the more unique discs, like the final 16-bit Platform Archive they had created in the early 2000s, as well as the very first MSDN release (from 1995, I believe, which fit on something like 14 CDs). I may still have "the very last of everything" somewhere. But I had tons of duplicates. No point in hanging onto those.
