Hint: if Apple allowed apps to run indefinitely in the background, it would be less than a month before almost every app "needs to run in the background", for user-unfriendly reasons. And battery life would drop to a couple of hours.

This is why I'm an Apple user. Hate regarding Apple's policies like "use a platform that lets the app function correctly" (ie. drain battery running in background just to do more tracking, or because every developer assumes THEIR app is so special that it must never be unloaded from memory, in order to open instantly when being swapped back to... weeks after user's last interaction). With hilarious frequency, the complaints people have about Apple are precisely the reasons I prefer their products.
