The free portion are things that are already written. Services are the thing that costs money and they include features, hosting, adapting, etc. Those aren't free.
Maybe I'm cynical but I see things that are technically free all residing within environments that aren't. I don't have a problem with that, I'm OK with commercial interests. They pay my salary. But we need to be realistic about the scope of free and how financially viable would it be to be "free".
