users may be more inclined to update apps
If the developers (of both OS and apps) would develop versions that just have the security fixes not new features. Also sorely lacking is the ability to easily roll back as well.
Was burned too many times early on after switching to Android many years ago I have had auto app updates off and only update when I really have to.
Two cases in point. Ironically both Weather apps.
Weather.com perhaps before their app was sold to IBM had a pretty good Android app. Then they improved it I guess and wrecked it pretty royally in my opinion anyways. Fortunately I had a backup of the older version(v4.2) and it continued to work for several years(some MINOR things broke, but 85% of the app was workable which was better than the new official version). I was actually quite impressed how long the older version lasted. I powered up my Note 3 just now with that app and it does not work anymore(no errors, just no weather data), but it did at least up until July 2019 when I moved to a newer phone as my daily driver.
On my newer devices I switched to Accuweather, which too had a really nice(in my mind anyway) user interface worked well, paid for the no ads version. Then recently they revamped it. Wrecked it again (check google reviews MANY complaints). Fortunately again I had a backup and reverted to the older version. For whatever reason since I downgraded the notification bar doesn't update automatically anymore no matter what I do, I have to click a little icon on the bar to get it to update. But it works otherwise and again is better than the alternative of using their new app. They started sending popups in the app to get me to upgrade but have ignored them. Not sure if I will get lucky enough to be able to use this older version in the years to come, or if I'll need to find another weather app.
