10 years ago, I found some software updates annoying. 5 years ago, I found most of them aggravating. Now, I find them to be outright harmful except for rare cases.
It's very common for (particularly mobile software) to just break the product entirely. Features I regularly used and depended on--sometimes even the main features--are just deleted. Gone, with zero chance of using it again. Sometimes ads are thrown in, adding a major vulnerability. Other times they reduce/cripple features, yet somehow worsen performance despite doing less. Sometimes they wipe data. Sometimes they update and suddenly require a google or facebook login to use "for convenience" (inconveniencing me who never needed to login before).
Updates before used to be bugfixes and cleanup, and major upgrades came out every year or two and you'd have to manually opt in to those by going to their site and downloading a new version, or going out and paying for it. Now your old, functional software is wiped from your system and replaced with a bad imposter using the same identity.
I'll begrudgingly install OS updates sometimes, but only weeks or months after release when all the downsides and upsides are easy to consider. The chances of me coming across some harmful vulnerability in the wild is far less likely than the reality of dealing with a harmful, work-destroying update. I haven't encountered the former in over a decade. I've dealt with the latter several times this year.
