Well, to be fair, you can disable notifications from apps since android 4.0 (which is a long time back)

And Android 6.0 and up should automatically disable background running apps (https://developer.android.com/training/monitoring-device-sta...) unless there is a good reason for them to be running

But apps can still work around these restrictions (even on iOS; for eg the facebook app was caught "accidentally" playing silent audio.) Even if that was truly a bug, the point remains that it's better to use the website unless you want something specific (offline access, push notifications, etc...)
