Were you subscribed to PlayStation Plus? The downloading and updating in the morning is part of the Automatic Update thing, which should only be happening if you're a PS+ member. And you can opt to turn that off, if you were.
I'm gonna initially answer in a very sarcastic manner which otherwise would come across poorly, so this is your disclaimer that I don't hate you or nuthin'.I've owned Judas since six months after launch. No, turning off auto-updates had never freaking occurred to me.
*exhales*
I exhausted every option available to me. I did it all. Eventually, I even unsubscribed from PS+. Not for performance issues, mind, but because my online friends began to stop playing co-op with me altogether and simultaneous with these events, the free monthly games selection began to routinely suck ass.
But none of that appeased Judas.
Judas' constant insatiable hunger for updates never stopped or slowed. If I ever agreed to download something, Judas wouldn't rest until it was done, so I just unplugged it when I wasn't using it (it would even turn itself back on --cold boot itself-- otherwise!), and I eventually stopped using it completely. After that, it just sat in a closet corner with a sheet covering it like some horrible forgotten thing for the better part of 2016, only being awakened once during that span to blitz through Uncharted 4 (honestly not a fan, which I never thought I'd say about a Naughty Dog game).
Meanwhile, my Vita has never once had betrayal on its mind, and my Xbox One has never lifted a metaphorical finger to do ANYTHING without my express permission in each instance. And so far, my PC has behaved itself barring a crazy amount of updates after the initial startup, which honestly I'd expected to happen anyways.
Judas was just pure evil in console form, and after Sony botching the releases of their various Xperia phones in America during that long but critical period where people like me still cared about that brand, their MASSIVE customer service fuck up regarding my Vaio laptop some years before (they refused to repair it and made me send it to Best Buy, who broke it even worse.
Twice.), and their willful abortion of the Vita before they'd even seriously tried to help it succeed (they gave up entirely after what, two years?), this string of betrayals by Judas was the thing that finally and fully axe-murdered my prior obsessive fanboyish love of Sony products beyond hope of redemption.
Sony done screwed up, and after all this time, I firmly believe they have no one to blame but themselves.
And Judas.
