While some may think I have misinterpreted the blog author (and I acknowledge this is a valid response), I still think that bug or nondescript "security fixes" is a powerful, fear-based mechanism to compel users to allow updates -- of any kind. And it therefore relevant to any discussion of "updates". Especially when it is common for these bug or "security fixes" to be inextricably mixed with non-security items such as "features" in such a way that the user must except the "whole hog", perhaps in some way similar to "omnibus legislation" in the US Congress.
I respect everyone's opinions whether you agree with me or not. I am just happy to see that some users may be thinking about "updates" and what they really are instead of blindly accepting them without ever pausing to think.
From my perspective every new "feature" that adds code is also introducing a new potential for a bug or security issue. I want programs and systems to get smaller not larger.
