The fun fact is that those people have 100+ apps on their phones, which run in the background, draining their batteries, tracking the sh*t out of them, never actually use them (get value out of them) and they think zero about their privacy (probably use gmail or the sorts). Someone asked me to install Viber and it had 30 pages of advertisers/data brokers. I won't share a bowl of poop with them (WhatsApp, Viber, etc.) "Meet them where they are" doesn't work if they are in a pool of privacy-poop.
I don't know about iOS but a modern Android will periodically delete permissions from apps you aren't using, the app stays installed but it's now just a harmless icon and wasted storage space as I understand it.
You also have the ability to easily setup a "Work profile" that's functionally like a second user with its own apps that don't talk to your normal profile apps, and you can shut the whole work profile off when you don't need it so the apps can't even run until you turn it back on. My preferred way of setting it up is with Shelter installed via FDroid.
You are preaching to the choir here :) My point is not for "us, the techies" and privacy-oriented people. My point is clearly for the 50%-60% that think that "we are trying to take their precious WhatsApp from them" and they don't understand that their car insurance is gradually 20% more expensive than others because they keep posting photos from bars on FB.
I keep 'lean' devices, the apps that I actually use, battery lasts from days to weeks (phone, tablet respectively) and NoRoot Firewall (on Android) makes sure that my phone stays 'silent' to the apps and target IP-addresses of my choosing.

This is wildly untrue on iOS. Perhaps people have 100+ apps. But the rest, not so much.
> Are they silently shut down/paused after a while?
Yes. This has been the case since 2008 when the first version of iOS supporting third-party apps was released. Background refresh allows some quanta of work do be done when an app is not in the foreground, but only limited things.
