This is provably false on iOS, yeah? iOS's backgrounding model means apps that aren't actively doing work don't "take up memory space". Apps that you never open are quickly throttled from all forms of background processing on a pretty aggressive timescale (I know this firsthand, it's been a major pain for one or two specific apps I've worked on). Push notifications are, as the name implies, a push service rather than a pull/polling service. Unused apps do take up storage space, but iOS 11 and newer automatically silently delete apps you don't use, keeping the user's data and the app icon around for when you open it again. In the settings UI where you can disable it, this is explicitly framed as only saving you storage space, rather than having performance benefits.
