But they can?

Source available can mean everything from "proprietary, you can look but you can't touch" to "this source code is licensed under Creative Commons Attribution 4.0".

This is exactly the problem. "Source available" refers to such a massively wide gamut of possible licensing scenarios that it may as well be meaningless.
