Anytime you do an update, there is a risk that the update will screw up the website. It can conflict with the theme you are using or other plugins.

I am against any FORCED update. I am there to do updates, not any automatic way. So in case there is a screwup/conflict…I am there to fix things.

I am sorry but there is never a reason for any plugin author, Automattic, the Tooth Fairy or even Santa Claus to essentially tresspass into my property (my website). I usually update within an hour or less whenever there is a core, theme or plugins update.
