I hate when Google Play download things without my consent

Websites install to my phone and behave just like native apps (Progressive Web Apps) and native apps don't need installing anymore and behave just like websites. (Instant Apps)
The lines are blurring. I don't know what to believe anymore.

My phone just randomly started installing "instant apps" by itself even though my settings are explicitly set to not auto download update anything. It's not even visible in my installed apps to remove. After a quick search it seems like Google is forcibly rolling out a new feature. If I wasn't looking at my phone I wouldn't have known. Thanks for eating my mobile data.

FUCK GOOGLE'S INSTANT APPS.
I know google is bad in general, but fuck Instant Apps in particular!
Doesn't matter if you've disabled them from every account you have, they will still update and install themselves no matter what! Doesn't matter if you're on wifi or on a mobile connection using data either!

What's even worse is that there is no trace given of these update - just a temporary notification while it's downloading and installing the update, then it's gone! Blink and you'll miss it.

Can't even get rid of this shite, because I have a few accounts tied to a project that are entirely based on google services :(
Fuckin' spyware
