He hates unitaskers in the kitchen because they take up finite space and money. These don't really apply to tiny free apps. It's like complaining about an extra key in a keyring you never use in a drawer you never open.
There is a 100x difference in size between different apps. If apps do little, they are often tiny.
A huge app that does nothing, that's a very different thing.
I'm an iOS developer. I have over 500 apps in iTunes ("Can you check this out please and tell me how much a menu like theirs would cost"), mostly not on my devices.
