Firstly, given that the default behavior outside of enterprise environments is to automatically install updates do we have evidence that this has been significantly problematic? If this is indeed a problem then there should be plenty of instances in the history of Windows Update.
There are plenty of previous cases where Windows Update has broken things. That's why a lot of us are so concerned. Been there, done that, spent the next several hours clearing up the mess, on occasion even resorting to physical media because the normal recovery mechanism was sufficiently b0rked that even booting that far wasn't happening.
Secondly, if the above case turns out to be valid (I'm no expert, that's why I'm asking) then is there any evidence to indicate that this would still not be resolved after a few months of deferring the update in question?
Severe problems like the ones I was thinking of above? No, to be fair to Microsoft, they have usually fixed those within a day or two. (Drivers are a different question entirely, but as we've determined, those are a different case and not entirely Microsoft's responsibility.)
But minor gremlins that mess something up for people with certain hardware or software combinations? Or updates that aren't really necessary at all, like the Win10 nag messages? I don't see any rush to get those fixed.
In any case, as the financial folks will tell you, past performance is not a reliable indicator of future behaviour. The fact is, if you trust Microsoft to get this stuff fixed and it does turn out that they can't or won't fix whatever issue is affecting you, your business is screwed. What manager or IT group wants to risk their business's ability to trade or potentially their own personal livelihood in that way, entirely unnecessarily? Why would any rational person do that, if they understand the other options available to them?
Right, so is the solution to proliferate the knowledge about how to resolve the problem or just bitch pseudonymously in web forum comments about the existence of it?
Once again, the problem isn't just this specific issue, it's the uncontrolled risk associated with allowing anyone to force software changes on a PC you rely on.
And if you think I'm only bitching about this pseudonymously on-line, you're crazy. Every business I work with (and a couple of family and friends who have asked) has been actively making plans to avoid winding up on Windows 10 for a while.
BTW, my comments on this issue are mild compared to a few I've heard when talking to the sysadmins at some of those businesses. The language some of those people used to describe Microsoft's attitude here isn't something you'd repeat in polite company, let's say.
