There are A LOT of people who ran out of space on their phones and can't install anything anymore. So if your app is 500MB, they'll first have to find 500MB worth of stuff to delete. If they really want your app, they'll look through the storage settings on their phone, and start deleting their biggest apps. So if your app is too big, many people won't even install it, and if they do, it'll be the first app to go if they need more space.
